The sensor circuit detects the sound causing the led to blink. Use the Sound Sensor to listen to great music, can combine many Led multi-color LED modules to create beautiful effects. The light intensity and sensitivity of the circuit can be controlled according to the requirements and the space to be used accordingly thanks to the potentiometer. The circuit is very simple without using IC, you need NPN transistor S8050, tip41, 1M 10k 1k resistor, 50k-200k potentiometer, 10µF capacitor, and sound sensor (microphone, mic). Make your own sound sensor circuit and decorate your room more interesting. Explain the working principle of the sound sensor circuit.
