The circuit was designed to produce a universal infrared switch with a single channel and ON/OFF feature to operate in 36 kHz to 38 kHz in the form of a remote control. Infrared – a portion of the ...

This circuit is low cost and can be constructed easily. By using this circuit, we can control any house hold appliance with the help of remote. This circuit is low cost and can be constructed easily.

If you’re looking for your first electronics project, or a project to get someone else started in electronics, [Vadim] has you covered. Back when he was first starting out in electronics he built this ...

This MEMS-based on/off switch is triggered by impinging IR photons, and remains in a zero-power quiescent state until that event takes place. Even the minute amount of current needed in slow, ...

Infra-red (IR) remotes are great, unless you’re in a hackerspace that’s full of crazy blinking lights and random IR emissions of all kinds. Then, they’re just unreliable. Some smart folks at Metalab ...
