Other Arduino Codes and Videos by Robojax
This video shows you how to turn an AC light ON with clap or your voice and Turn it off with another clap or shout. This code is basic version where digital output of the module is used. Please see other version where actual Analog sound values is used to control light.
This video has two Arduino code (sketch)
1-Baisc Code using Digital pin
2-Advanced Code using Analog pin
/*
* This is the Arduino code for Sound module for Arduino (basic)
This video shows you how to turn an AC light ON
