This Arduino-based project allows you to control an AC bulb using a clap sound. It uses a sound sensor to detect claps and a relay module to safely switch high-voltage devices like a bulb. This is a ...

When a clap sound is detected, the relay toggles the bulb ON/OFF. Useful for smart home and assistive tech. Clap sound is detected by the sound sensor. Arduino reads the signal. Relay switches the ...
