This code and diagram will show you how to make a single LED react to music with a sound sensor, its based off of GraziCNU tutorial on instructables.com

Components:

 

  • Arduino Uno
  • 5 Jumper Wires
  • Breadboard
  • Sound Sensor
  • LED light

 

Instructions:

  • Wire the ground pin to ground on the sound sensor (GND)
  • Power pin (VCC) to 5V
  • Output (OUT) to A3
  • Connect the Anode (+) of the LED to VIN
  • Connect Cathode (-) to Digital pin 9
