Sound – Audio Projects

Music Reactive Infinite Mirror

Hi fellow makers! This is a project I’ve been working on for my Makerspace class at Collégial international Sainte-Anne. I truly hope you will like it!

*I’m sorry about the focus being bad. It was almost impossible to obtain a great focus since the LEDs were constantly flashing.*

The topic to which this project is related:

Since I am a musician myself, music always had been part of my life. I thought it would be really cool to have something of a decoration that reacts with music. I thought, how cool would that be if you could just stick an LED strip in your room that reacts with music. After looking forward to this, I realized this project has already been done. I then thought, what if we put this system in an infinite mirror. Thus, I created an infinite mirror that interacts with music.

Description of the project

The main idea behind this project is a rbg LED strip that is activated by sounds. The LEDs were programmed to vary in intensity depending on the different sounds that are picked up by a small microphone linked to the system. The LED strip was then cut and put in an infinite mirror, made with a regular mirror, a tinted glass and a photo frame.

How to use the final result of this project

To use this object, you need first two source of electrical power. You need a 5V supply, that can be provided by the USB port of your computer. You also need a 12V supply that be provided by a battery of a power supply. After, the LED strip embed in the infinite mirror needs to be connected to the breadboard where the connection of the circuit has been previously made. Then, the Arduino needs to be connected in the computer, and the system will be instantaneously activated, reacting to any sounds.

The purpose of this new object and some applications fields

This object could be only as a decoration for various places. It could be hang in the living room or in a bedroom. It could also be used in the entertainment field. To artistic exposition events to party, this object could be very interesting to use. The technology behind this project could be developed and used in musical events such as in festival or music shows to improve the visual effects and create a symbiosis with both sound and sight.

Files needed for the realization of this project

The only file needed to complete this project is the code programmed on Arduino. It can be found in the embed file tab of this step. A photo of the code and the code itself can also be found in its appropriate step.

Step 2: Removal and Cleaning of the Glass and Mirror

1- Remove the glass from the frame like shown in the video below.

2- Clean both side of the glass the soapy water

3- Do the same with the mirror.

Note that in my case the mirror was recuperated. I needed to tear the paper behind the mirror frame. I then took out the mirror by removing the small nails that was holding it. I then cleaned it the same way as the glass.

Step 3: Applying the Tinted Film to the Glass

1- Take the small carton box and clean (you want to make sure that no granule or residue are on it). Clean as well the surface you will be working on.

2- Take out the glass and clean it using the glass polisher and the microfibre linen.

3- Then, lift the glass carefully holding it by its the corner and drop it on a small box cleaned before. Leave the box and the clean glass aside.

4- Take out the roll of tinted film and cut a slightly bigger piece than the glass.

5- Then, detach the four corners of the film and stick 4 scotch tape piece (one on each corner) between the tinted film and the small plastic protecter.

6- After, remove slowly the plastic protecter by constantly applying soapy water with the vaporizer. Make sure that the tinted film is fully covered of soapy water (they should not be dry spots).

7- Take the clean glass and leave it on the clean surface. Apply a sufficient amount of soapy water on it to be completely covered.

8- Take the tinted film with soapy water and drop it carefully on the glass with soapy water. It is very important for the soapy side on the tinted film to be applied on the soapy part of the glass.

9- With a gift card or an old credit card, take out all the air bubble remaining between the tinted film and the glass.

10- Let rest and dry the glass for couple of hours (at least 2 according to the instructions)

Step 4: The Connection of the Circuit

*Photo above are supporting each steps*

For this particular step, I suggest you to stay organized and to choose the colour of your jumper wires according to their function. For instance, I am using the red for all the positive ports. I am using the black for negative, yellow for the bridge between LEDs and transistors and white for the wires connected to the Arduino.

1- Take your bread board and make a bridge with a jumper wire (M to M) between the two positive column.

2- Plug the a jumper wire in the positive column as well as another in the negative column. These will be used to connect the set-up to your power supply.

3- Make a bridge between the positive column (the one on the left of the ABCDE lane) and port A27.

4- Plug the adaptor for the LEDs (which has 4 pins) in B27, B28, B29, B30.

5- Plug a jumper of a different colour from C28 into F24.

6- Plug a jumper the same colour as in #5 from C29 to F29.

7- Plug a jumper the same colour as in #5 from C30 to F35.

8- Plug one of the transistor (which has 3 different pins) in H24, H25 and H26. The flat face of the transistor with its identification should face the wire pugged in F24.

9- Plug one of the transistor in H29, H30 and H31. The flat face of the transistor with its identification should face the wire pugged in F29.

10- Plug one of the transistor in H35, H36 and H37. The flat face of the transistor with its identification should face the wire pugged in F35.

Note- You can cut the long metal ends of the resistors with the electrician pliers to make them fit better into the breadboard.

11- Plug the 200 ohms in J26 to the negative column.

12- Plug the 100 ohms in J31 to the negative column.

13- Plug the 560 ohms in J337 to the negative column.

14- Plug a jumper of a different colour in J25. The other end will be eventually plug into the Arduino.

15- Plug a jumper of the same colour as in #14 in J30. The other end will be eventually plug into the Arduino.

16- Plug a jumper of the same colour as in #14 in J36. The other end will be eventually plug into the Arduino.

17- Plug a jumper the colour of negative you chose into the negative column. The other end will be eventually plug into the Arduino.

Step 5: The Connection of Arduino and Microphone

*Photo will support each steps*

1- Plug the jumper wire from J25 into the 3rd pin of the Arduino.

2- Plug the jumper wire from J30 into the 5th pin of the Arduino.

3- Plug the jumper wire from J36 into the 6th pin of the Arduino.

4- Plug the wire from the negative column (the one to the right of the FGHIJ lane) into the the ground (GND) pin of the Arduino.

5- Plug the 3 female-female jumper wires into the Digital Output (DO), Positive (+) and Ground (G) respectively.

6- Plug a male jumper wire into the female end line up with the Digital Output (DO) and plug it into the 7th pin of the Arduino.

7- Plug a male jumper wire into the female end line up with the positive (+) and plug it into the 5V pin of the Arduino. (This pin is on the other side of the Arduino. To recognize it, there is a white band that indicates POWER)

8- Plug a male jumper wire into the female end line up with the ground (G) and plug it into on of the GND pins of the Arduino. (This pin is on the other side of the Arduino. To recognize it, there is a white band that indicates POWER, next to the 5V in step #7)
