In this video, I show you how to make a clap switch using double BC547 transistors and connect it to a PC817 optocoupler to control a touch switch module. This unique setup allows you to activate all the features of a touch switch just by clapping!
How It Works:
The BC547 transistors act as a sound detector circuit to sense clap sounds.
The output is sent through the PC817 optocoupler for electrical isolation and signal transmission.
The touch switch module receives the signal as if it was touched, giving you full functionality with just a clap.
Applications:
Wireless light control
Smart home automation
Hands-free switch activation
