I built a circuit that detects sound and sound a buzzer using ATmega328P external interrupt. It can be used in application like automated library noise alert system for school or college. Silence is critical in libraries, and this circuit monitors…
Controlling LED-based signboards based on ambient light levels can significantly improve their efficiency and usability. An automatic light control system can ensure that LEDs turn on only when it's dark and turn off during bright daylight, savi…
Operational amplifiers (op-amps) play a crucial role in various electronic circuits, offering amplification, signal conditioning, and comparison functionalities. Two commonly used op-amp ICs, the LM358 and LM393, have found widespread application a…
