In this illustration we will going to wire the microphone module, relay and the Arduino board. These project is compatible on most common microcontroller, the main objective of this project to make a sound activated switch or a clap switch. The light will turn on if sensor sense a sound then triggering the relay which is connected to the microcontroller.
