So, let us make the Simple Sound Reactive LEDs Circuit. A music-reactive LED circuit is a basic electrical circuit that responds to altering sound levels, generally from nearby playing music, and reflects the change level of intensity of the sound signal as blinking LEDs. Hardware Components. The following components are required Step 4: Arduino and Pulse-Wave Modulation. An Arduino Uno is perfect for this project because it can handle the load of the LED strip, you can write multiple programs depending on what particular behavior you would like to see from your LEDs and besides the standard General Purpose Input/Output (GPIO) pins, it also has Pulse-Width Modulation (PWM) pins.

Create an immersive audiovisual experience with our DIY Music Reactive LED system, synchronizing aptivating light displays with the rhythm of your favorite music using Arduino. // Analog pin connected to the sound sensor 2 const int ledPins [] = resistance(R) = (power supply voltage - LED voltage drop) / LED current The typical recommended LED current is 20mA, our power supply voltage is 9V, and the LED voltage drop for a clear blue LED is 3.0V. This results in: (9-3)/0.020=300 ohm Of course this doesn't need to be exact, a 330 ohm resistor will work fine here.
In my setup I used two 5m LED strips from Amazon. Each of these strips requires a 2A supply and because I had ordered separately I got two 2A supplies. However you can just use a single 4A supply to power your circuit and your strips. Since I have the circuit with two supplies I will list components according to that. 1> 2 x 5m Led Strips amazon
