Introduction: Sound Reactive Strip Led

Picture of Sound Reactive Strip Led

Hello,in this instructables I will show you how to control a led strip with music!. I put this led strip in my room,near my Playstation 4 and my speakers, so I created also an amazing illuminated gaming station. This led strip reacte when there is music,or simply a sound. In fact I use it also when I play videogames:while I'm shooting in a action videogames, the leds reacte and the result is amazing. In the final step there is a link that show the final result. Check the next steps!

Step 1: What You Will Need:

Picture of What You Will Need:

- LED strip

-Arduino uno

- sound module


- 9v battery/powerbank

- some wires

-adaptor to power the strip

Step 2: Wiring

Sorry for the quality of the image ,but I had many problems with the fritzing sketch. There is a file attached in this step so you can download the sketch for a better quality of the scheme. In the sketch I idn't find a sound sensor so I took a casual sensor that rappresent the module.

Sound sensor:

The first pin is the signal: S>digital pin 7

The second pin is the voltage: V> 5v pin

The third is the ground: G> gnd pin

Step 3: The Code

Picture of The Code

#define LEDstrip 9

void setup()

{ pinMode(7,INPUT);

pinMode(LEDstrip, OUTPUT);


.void loop()

{ boolean soundstate = digitalRead(7);

if (soundstate == 1) {

analogWrite(LEDstrip, 255);




analogWrite(LEDstrip,0); }


Step 4: Turn Up the Speakers!!!

The project is finish!!! In only 4 steps I show you how to make a " disco" in your room with "disco light". Now you have almost finish....the only thing you need to do is...TURN UP THE SPEAKERS AND DANCE!

I hope you liked this project,comment and see you next time!

Here there is the link for the final result:

then do nothing.

make the IBLE better and put it in there.!

jekob (author)WannaDuino2016-10-14

thanks for the criticism , I will improve myself about making instructables

WannaDuino (author)2016-09-14

verry bad IBLE, sorry

its a nice one if you realy took time and efford,you clearly see this is a quicky, of a already working build.

sorry friend,but we al must help eachoter,so dont take it to hard and do your magic

where should the power plug go and where should I hook up the relay? could you please send me some close up pictures of your setup

dj_segfault (author)2016-09-11

Could you be more specific than "Sound module"? That's not very helpful. And is that a solid state relay or mechanical?

Ehy I'm sorry for the misunderstanding. Here there is a link that show you the sound sensor and rele on amazon so you can understand better what tipe of sensor are. RELE:
