I, perhaps, the author of the lesson, I am not a Yarym fan of Justin Timberlake, but I could not not notice the stunning graphics in his musical clip to the song LoveStoned. This lesson will teach you how to create a similar effect using only the good old Photoshop.
That's what we will seek:
Materials for the lesson:
Step 1.Create new document The size of 1024x768 px, the background color is black.
Step 2. Open the image of the equalizer. I highlighted a black background image using the tool Magic wand (Magic Wand Tool) and deleted it by clicking Delete.Despite the fact that black corresponds to our chief background. Now, click on the area surrounding the equalizer, and invert (Ctrl + SHIFT + i) isolation so that only rectangular forms that make up the image of the equalizer were selected. Choose the main color of blue (80D2FC) and fill our selection by pressing Ctrl + Backspace. Finally, duplicate this layer, and go to Editing\u003e Transformation\u003e Rotate 180 degrees(Edit\u003e Transform\u003e Rotate 180Gradusov) then move the copy, as shown below.
Step 3. In the layer panel, we highlight both layers with an equalizer and click Ctrl+ Shift.+ E.To merge them into one. Now with turning the resulting layer 90 degrees - we go to Editing\u003e Transformation\u003e Rotate 90 degrees clockwise(Edit\u003e Transform\u003e Rotate 90 CW). Now copy the layer several times (Ctrl + J) and post equalizers one under another. Having done this, combine the original layer with all duplicates.
After spending all these settings, make a copy of the Blue Path from Equalizers, it will still need it. Hide it for now.
Step 4. Duplicate all this path and click Ctrl+ T. - We switched to mode Free transformation. From above on the right on the screen you can see the transformation panel. We need to move our row of equalizers to the right - for this we increase the number in the column X, click OK - and our track moved to the right:
Step 5. Interesting move, isn't it? With the help of the same commands, make five identical columns as shown below. Making them, drain it all in one layer.
Step 6. Did you merge all the layers of the equalizer? Now go editing\u003e Transform\u003e Perspective (Edit\u003e Transform\u003e Perspective) and drag for one of the upper edges towards the center. If necessary, make the bottom edges wider. Click OK. We got here such a track:
Step 7. Add a layer mask. This can be done by clicking on the "Add Vector Mask" icon on the layers panel, and you can in the menu Layers\u003e Vector Mask\u003e Show All (Layer\u003e Add Layer Mask\u003e Reveal All). Now the black brush with soft edges will pass at the bottom of our "path".
Step 8. Create a new layer (Ctrl + SHIFT + N) and a large white brush, again with soft edges, we will apply a few white spots on the "way". Change overlay mode (Blend Mode) on Overlapping (Overplay) for easy lighting effect.
Step 9. Now select your equalizer layer and apply the external glow parameters for the layer shown below. Now reduce the opacity (opacity) of the layer approximately 50%.
Step 10. Now duplicate your layer with equalizers, and move the duplicate below the original. Apply Filter\u003e Blur\u003e Blur in Gauss (Filter\u003e Blur\u003e GAUSSIAN BLUR), and then set Overlay mode (Blend Mode) layer on Hard light (Hard Light) and reduce opacity (opacity) approximately 30%.
Step 11. Closed Ctrland by pressing the LKM on the mask of the original layer with equalizers, lay out it. And now, making an active layer with blur, create and on it the same mask. To do this, simply click the vector mask icon in the layers menu (F7).
Step 12. Now create a new layer at the very top. Choose a black color main and fill this layer by pressing Ctrl+ Backspace.. Now go B. Filter\u003e Rendering\u003e Clouds (Filter\u003e Render\u003e Clouds). Put Overlay mode (Blend Mode) layer on Lightening the basics (Color Dodge).
Step 13. Duplicate your layer with clouds. We must get a more intense effect. Select your layer with equalizers and tools Magic wand (Magic Wand Tool) Click on the Black Section. Now invert your allocation so that the "path" was selected. Return to your second layer with clouds and press Delete, then reduce opacity (opacity) to 10%. We received an additional fog at the edges of the equalizers.
Step 14. Create a new layer. Now select a brush big size With 0% rigidity and 100% opacity. Choose a light blue color (for example, 77D1FF). Make a few big spots. Reduce the opacity (OPACITY) of this layer to 30%.
Step 15. Now duplicate your original layer with clouds and move it above your layer with large brushes. Overlay mode Leave Lightening the basics. Now reduce the opacity (opacity) layer with brushes up to 20%, and the layer with clouds is up to 45%. And also applies to a layer with a brightness of Gauss in 200px, to somewhat "smeared" the effect ( Filter\u003e Blur\u003e Blur in Gauss (Filter\u003e Blur\u003e Gaussian Blur)).
Step 16. Now insert the image of a person in the center of your image. Man is on a white background, so it is very easy to highlight, pressing Magic stick On the white background, invert the selection (CTRL + SHIFT + I). Copying a person (Ctrl + C), go to our document, insert a person (Ctrl + V). A man must be on the topmost layer! Now change Overlay mode (Blend Mode) layer on Soft light (Soft Light) and use the tool Eraser (Eraser) to erase his legs, allowing him to merge fine with the equalizer.
Step 17. Now duplicate your layer with a person and change Overlay mode (Blend Mode) in duplicate on Normal(Normal). Now any way known to you make the selection of light parts of the photo, in which case the face and shirt. Copy this site to a new layer (Ctrl + J), and the previous layer (the whole person and normal overlay mode) hide or delete. We return to the bright areas - we do not need a tie (it is dark). Remove it Eraser. Gently, do not hook a shirt!
Step 18. Now for layer with light areas we go to Image\u003e Correction\u003e Dispute (Image\u003e Adjustment\u003e Desaturation). When you choose in the same menu Color balance (Color Balance) and apply these settings:
Step 19. Now it starts the most interesting! Remember, I asked you to save one of the paths. He is needed now. Transfer it to the top and tap the size so that its height is equal to the height of the person. Reduce a little layer opacity (about 80%). Make two copies of this layer and hide.
Return to the original path. Put it right in front of a man, go to Editing\u003e Transformation\u003e Deformation (Edit\u003e Transform\u003e Warp) and do something like a wave (see Krina below). Make one duplicate visible, put it on the left and do from the same thing, but on this layer where there is a narrowing in the center, there should be an extension. I just can not imagine how this is different to explain, simply, look at the screen. By making the first duplicate wavy, go to the second and, by placing it on the right, achieve similarity with the screen below.
Step 20. Now drain all your duplicate layers of equalizers together, and go to Image\u003e Correction\u003e Brightness / Contrast (Image\u003e Adjustment\u003e Brigthness / Contrast) and make your brightness (Brigthness) to -100 and contrast (contrast) by +100 to make your image black. Need to add a layer sharpness, for this we go to Filter\u003e Sharpness\u003e Sharpness+
(Filter\u003e Sharpen\u003e Sharpen More). Edges become clearer and then we use the tool Magic wand With a tolerance of 50 by clicking somewhere outside of our equalizers.
Now invert the selection (CTRL + SHIFT + I) and hide our layer with equalizers. We have allocated all three deformed equalizers. Returning to our layer with light parts. However, if we just click Delete., I will remove too much. Take Eraser (E) With soft edges and opacity (opacity) about 20% and carefully remove only those parts that you think. Important: Do not overdo it with a face! Without removing the selection, go on a layer with black parts and work Eraser there.
From the translator: Of course, my role is not great here - I'm just a translator. But here is my opinion - the effect on clothes is not too similar to the one in the clip. I advise you to achieve the best use is not an image of the equalizer, but to create any lines yourself and already, copying them, remove parts of clothing.
Step 21. Now create a new top layer and use your tool. Pen(Pen Tool) to stretch the line near your person. Make sure your current brush is 1px in size, 100% in stiffness, and the main color of B6Fefe. Having draws the pen on the pen, click PCM on it and select Perform circuit stroke (Stroke Path). If your line does not suit you something, you can always change its shape with Free transformation (Ctrl + T). Finally, we duplicate this layer and move the duplicate slightly below the original. Reduce the width of the second layer so that the lines differ slightly from each other.
Step 22. We drain both layers of lines together and apply Layer style (Layer Style). In settings External glow Expose what is shown below. Take a small soft Eraser (E) and a little erase the edge of the lines. And now reduce the opacity (opacity) of the layer to 80%.
Step 23. We go B. Edit\u003e Transform\u003e Scaling (Edit\u003e Transform\u003e Scale) to shift our lines slightly closer to each other. Now Eraser Remove parts of lines that go before man's legs. Now we create a new layer above all the others and use round white brushes. Gradually reduce the opacity (opacity) to create the effect of gradually disappearing the edges of white lines. Now just put Overlay mode This layer is on Overlapping (Overlay), giving lines a cool light effect.
For those who remember the eighties of the last century, this project will undoubtedly cause pleasant memories when each part of the audio equipment has abounded by LED indicators, especially a graphic equalizer or "Graphic EQ".
This project uses MSGEQ7, on the basis of which we will create a 2-channel graphic equalizer (in reality a simple spectrum analyzer). For the first time in the last ten years I will use Arduino Uno R3, Arduino Development Wednesday and "C" programming.
To make the above device, you will need a specific tool, basic knowledge of electronics and the following components / libraries:
1. 3 Explorer with dad / dad connector, which are shown in the image above (red, black and green) to connect a photosensitive resistor (LDR).
2. 5-wire dad / mom connector, which is also shown in the image above (red, black, blue, green and yellow) for connecting the 8x8 LED matrix.
3. 2 LED matrices 8x8.
4. 1 Resistor with a denomination of 22 com.
5. 1 ARDUINO UNO controller.
6. 1 SPECTRUM SHIELD.
7. Arduino LedControl Library from the Git Hub resource. github.com/wayoda/ledcontrol/releases.
The diagram is designed to display the left and right audio channel. Seven columns of each matrix 8x8 represent a large-scale analogue of the following frequency components present in the audio signal track at any transition state in time.
16 kHz, 6.26 kHz, 2.5 kHz, 1 kHz, 400 Hz, 160 Hz and 63 Hz.
The last column represents the moving average value of all frequency components.
Audio is served on Spectrum Shield Spectrum via 3.5 mm sockets on the board, other jacks are used to transfer this audio to the dynamics.
Basic scheme for Shield Spectrum Shield can be found
The LDR light sensitive resistor is used for the 8x8 LED Matrix Software Dimension in the event of a level drop. external lighting For more contrast image.
Step 1: Detailed design
The above image shows how to connect the remaining components of the scheme to Spectrum Shield Spectrum and two LED matrices 8x8. There is a copy of the Sketch Arduino used to control the display. Sketch is attached below.
Step 2: Installing Components on Universal Male
For this procedure, there will be a little experience in electronics and special tools, such as soldering iron, pliers, scissors, etc.
Now, the developed program, I associated with a scheme and a dump truck, which is accuracy over Arduino Uno and Shield Spectrum Shield.
At the end, I got the conclusions on LED matrices 8x8 so that they became perpendicular to the board and could insert into the contact holes on the printed circuit board.
The detailed image is shown above.

Many car owners try to give their own car of the parameters that are not similar to others. Some try to improve specifications His car, in some cases, bringing the indicators of the serial car almost to the characteristics of sports cars. Others are trying to increase the permeability and so good in terms of SUVs. Such refinement relate to tuning, and they "suffer" a large number of car enthusiasts - from only received driver's license Prior to "solid successful decades."
But such a direction as a facelifting, which for some reason is also attributed to tuning, more inherent in young people. They try to externally give the individuality to their cars by replacing bumpers, hitch of spoilers, kites, vinyl or airbrushing, the arrangement of the car with high-quality acoustics.
A special place in the facelifting is occupied by the equipment of the car with additional lighting. In addition to the replacement of regular optics on more "advanced" and modern, often a car is completed with additional light technology. - Now the phenomenon is not as rare.
Recently, another type of removal of the car, which had to do with lovers to give the specialties to their car - equalizers, appeared.
Features Equalizers
Blue Equalizer on the rear window
This equipment on the car's glass creates a luminous image of an equalizer, which pulsates depending on the sound frequency of the music. In essence, this same equalizer, which usually has every car radio on its display, but only significantly increased in size. In itself, this equipment does not carry any positive function, it simply translates the sound of music into the light indication, which. Therefore, do not confuse this species Equipment with an equalizer, which produces a fine tuning of the sound of music.
The form of the image in such an equalizer can be different. The most common columns are responsible for a certain frequency of sound. The coloring of such equipment may be the same type - all of them have one color, such equalizers are depicted with only increasing or decreasing monochrome columns divided into segments.
Multicolored equalizers are found. Each column has several types of color segments, each of the colors is responsible for a specific sound frequency range. For example, the sound of a low frequency is painted red, medium - green, and high - blue.
Some expensive equalizer models may include several types of lighting images, for example, on the sides there are round multi-colored light indicators, and in the center - columns.
The size of the equalizer can also be different. Some have small dimensions and are suitable even for use on side glasses, the other are enough dimensions and can cover the rear window completely.
The most convenient place to install such equipment is the rear window. His dimensions Allow the car to equip the car with large-sized lighting equipment. Some also set equalizers on side glass rear doors, but it is not always justified.
The principle of operation of the automotive equalizer
Equalizers on the rear window of the car have a relatively simple design. There is a tape on which LEDs forming column segments or circles are fixed. Moreover, the tape and the LEDs attached to it are usually transparent, so do not interfere with the ven in the car during the daytime. The number of tanning segments depends on the voltage that the control unit submits on them. The block itself is equipped with a very sensitive microphone, which catches the sound in the cabin.
Installation of equalizer
This microphone is adjusted voltage, which is then fed to LEDs. With a weak sound of certain frequencies, the voltage is small, which is shown only by the lower segments of columns. With increasing sound frequency, the microphone begins to skip the voltage more, which is started to light up more segments.
The entire design of this equipment consists of a ribbon with LEDs, wiring, control unit, equipped with a switch-on key and adjusting the microphone sound susceptibility, as well as an adapter to connect to on-board network Auto. This is the feature of the equalizer design. It does not require connecting to the car, its work depends on the volume of the sound of music in the cabin.
Installing the equalizer does not require special knowledge, so each can do it.
Ribbon with LEDs around the perimeter is equipped with a sticky stripe closed protective film. To install this tape, it is enough to remove the film around the perimeter and lean it to the rear glass of cars with innerSo that the sticky band grabbed. If it was not possible to glue exactly exactly smoothly, you can carefully separate the ribbon and stick again.
Then this tape is connected to the control unit. From the block, there is a sufficiently long wire, so that when laying hide it through the cabin, in order to avoid damage. It is necessary to lay the wiring so that the control unit turns out to be in the driver's reach zone. The best option Is a dodge boxing between the front seats. There this block will not interfere. Wiring to accommodate this block between the seats should be enough.
Usually, the washing of this equipment is made from the cigarette lighter socket. To do this, complete with the equipment there is an adapter for connecting. One end of this adapter is connected to the control unit, and the second is a special adapter to the cigarette lighter socket.
This is the whole connection sequence. It will only be necessary to check the performance and adjust the sensitivity of the microphone. To do this, connect the equalizer to the on-board network and turn on the power to the control unit. Then you should enable music on the radio and the wheel adjustment to select the microphone sensitivity.
To establish this equipment is easy, and considering that LEDs are used as light elements - then there will be no significant drawdown of voltage in the network.
Looking a light equalizer on glass, of course, beautiful. But it is worth considering that this is ordinary lighting equipment that works well only in the dark. Therefore, if the car is rarely operated in the dark, and the owner itself is not Meloman and does not like loud music in the cabin - then the equalizer is essentially not needed.
Finally, it is worth saying the legality of the use of light equalizers by car. In the rules road There is no point to prohibit the use of this equipment, therefore the penalty is not provided for it, although it is possible that it will soon appear.
However, the accident may indicate that the equipment has become a distracting factor, and this condition already provides a fine. But here you also need to prove that it is the equalizer that caused an accident.
ATTENTION OF USERS OF ELECTRONITY SITE The site seems simple in the assembly seven-band graphic equalizer. Externally, the equalizer is seven columns (by the number of strips) from the LEDs of different colors located in the order of the colors of the rainbow. In each column 10 of the LEDs - 10 signal levels.
Device concept is shown above. The audio signal from the release of the music center, the sound card of the computer or the smartphone enters the input of the MSGEQ7 specialized chip. This Mixed Signal Integration integrated circuit is a 7-channel spectrum analyzer in the DIP-8 housing and 1 mA consumption current, besides. MSGEQ7 is capable of the input audio signal to highlight the frequency bands of 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz and 16 kHz:
MSGEQ7 is controlled by two digital inputs RESET (output 7) and STROBE (output 4). After the starting pulse RESET, it is sufficient to submit seven gating pulses to the StroBe line, as a result of which after each gating pulse, the output of OUT (output 3) will appear a voltage proportional to the content of one of the seven frequency bands in the audio signal.
The MSGEQ7 microcircuit output is connected to the LED LED LED LED microcircuit input. This microcircuit has ten outputs, the state of which depends on the input level. The scheme is controlled by the ATMEGA328 microcontroller, I decided to use the ready-made Arduino Nano board. There are many projects on the network using more than seven LM3915 buildings. I decided to use dynamic indication and one LM3915 chip. The microcontroller generates the RESET signal for MSGEQ7 and then issues seven strobe signals strobe. At the same time, it includes one of the transistor key columns of our indicator and this column displays the signal level from LM3915, which is connected to the rows of our indicator.
I used seven-seven LEDs (red, orange, yellow, "warm white", green, blue and pink-purple) to display all seven frequency bands. Since the LEDs of different colors have a different supply voltage, different current and different brightness, in order to obtain the same light stream when working on our screen, I used the possibility of the LM3915 chip to set the output current. Each time switching the column, the microcontroller, depending on the number of the column using PWM (PWM) and a simple RC filter, forms voltage on the outputs 6 and 7 LM3915, corresponding to the required column brightness. Thus solved the problem of uneven brightness different types LEDs. The only thing that took place is to raise the frequency of ARDUINO with default 500Hz to 64 kHz (the first two lines in the SETUP Sketch section).
As far as I know, sometimes not completely high-quality copies of MsGeq7 come across. Characterize their noises at the outlet even with a grounded entrance. Those. Even in the absence of a signal on the screen, chaotic emissions will be visible. Apparently I got exactly such a chip. Therefore, I additionally start the output of the OUT to the microcontroller ADC (A7). Using multiple lines of code, the microcontroller analyzes the input signal, and suppresses the noise display, simply not including the column key.

As noted above, I used the Arduino Nano fee - the only thing I had to "modify", it is to fall a protective diode for USB nutrition and replace it with a jumper. On it "settled" the voltage and the scheme worked unstable. Also, there is also an electrolytic capacitor with a capacity of at least 1000 mg in order to be in the moments when almost all LEDs are burning on the screen, the voltage on the USB bus did not find it. It is also worth noting that when dialing a circuit from a USB computer, it is better to use a USB hub with external power, it minimizes interference via USB bus. The circuit board is not developed for the equalizer, the entire design is assembled on two dummy cards. On the video below you can see the performance of the equalizer.
