Clap Switch Timer Circuit | Auto ON/OFF Sound Sensor Project | BC548 Transistor DIY Electronics

This is a Clap Timer Circuit that turns ON with a hand clap and automatically turns OFF after a few seconds. The circuit uses BC548 transistor, 1K, 10K, 100K resistors, 2.2uF & 220uF capacitors, MIC, and LED. This project is perfect for DIY learners and school electronics experiments.

In this video I explain:
• How the clap sound activates the MIC
• How BC548 amplifies the signal
• RC timing control for automatic OFF
• Full circuit explanation
• Live demo and testing

Components Used:
BC548 Transistor
1K, 10K, 100K Resistors
2.2uF & 220uF Capacitors
Electret Microphone
LED
3V–9V Power Supply
