Introduction: Clap on Clap Off Switch Using BJT's
Are You Super Lazy? Ever Wished You Could Turn ON/ OFF Your Room's Light With a Simple Clap? This Insturctable Will Help You to Do So! You Will How To Create a Simple Circuit Which Can Control Any Electrical Appliance in Your House Which Draws 10 Amps or Less on 240VAC!! Just Follow Some Simple Steps Below:-
Step 1: Watch the Video
You Can Watch The Building Process of This Circuit in My Youtube Video! You can Find the Video in My Channel "ElectroMaker".
Step 2: Have a Look at the Schematic
Clap Switch Part List:-
