RGB SOUND REACTIVE LED STRIP

Introduction: RGB SOUND REACTIVE LED STRIP

About: I am from mechatronics department. Currently doing my BTech from Manipal University Jaipur and i am an robotics enthusisast.

In this Instructable I will be showing you how to create a sound reactive LED system. In this clip, I used a single color LED strip, but you you can use a single LED, multiple LEDs wired together, single color or RGB LED strip, it just depends on what you are trying to build. The set up is fairly simple, the component list is fairly basic so if you are a tinkerer you should already have the majority of the materials laying around.

In the following link you will see the entire setup. Obviously you may arrange it anyway you would like, I just kept everything close and compact for the sake of an easy video.

Step 1: COMPONENTS

Arduino Board -- https://goo.gl/f3pdKS

Sound Sensor -- https://goo.gl/bToAP7

LED Strip + Adapter -- https://goo.gl/5nx84s

Mosfet IRFZ44N -- https://goo.gl/5nx84s

Transistor BC547 (Optional)

10k Resistors -- https://goo.gl/5nx84s

Breadboard -- https://goo.gl/5nx84s

Jumper Wires -- https://goo.gl/5nx84s

Step 2: CONNECTION AND SCHEMATIC

As you can see i the schematic, i used arduino uno instead of arduino nano. You can use any of them the code remains the same.You can make make the connection by referring to the video below.I also used a LED separately to see if the sound sensor was working correctly while i was doing the connections.

Step 3: Arduino Code and Upload

int soundsensor = 3;
int led = 7;

void setup()
{ pinMode (soundsensor, INPUT);

pinMode (led, OUTPUT);

}

void loop()

{ int sensorvalue = digitalRead (soundsensor);

if (sensorvalue == 1)

{ digitalWrite(led, HIGH); }

else

{ digitalWrite(led, LOW);

}

}

Step 4: Pick a Song!

I had setup my room.Wait for the video for 2 sec after it starts.

    It works with anything that has an audio output.
