Here are the 2 simple circuits named clap switch circuits which are based on clapping. These circuits are useful in switch ON/OFF any devices by just clapping without any movement from your place.

A load switch is an electronic switch. It works like a relay to power supply rails in systems, but it has no moving parts. Load switches are increasingly found in today’s portable electronic devices, ...

A little over a year ago, I had a project that required driving an RF single-pole double-throw (SPDT) coaxial switch either by transistor-transistor-logic (TTL) pulses sent by an external source or by ...

A simple circuit is a chain of different parts with wires and switches which allows electricity to flow around. All electrical appliances use circuits. For electricity to flow correctly, the circuit ...

I needed a simple LED indicator showing that a particular voltage level had been reached—specifically, that a capacitor had charged to a particular potential. I was convinced that there must be a way ...
