Introduction: RGB SOUND REACTIVE LED STRIP
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
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.
