Instead of going with an IR receiver module you’ll build your own using a photo-transistor and an operational amplifier.

Burglar alarm assembly Assemble the transmitter and receiver-cum-alarm circuits on two separate general-purpose PCBs and house in suitable cabinets. Mount the units on the opposite sides of the ...

Summary The IRTR module presented here features a fixed-gain, 38-KHz modulated infrared receiver and a corresponding infrared sender with oscillator circuit to make cool infrared projects such as a ...

Tired of loud TV ads? In 2012, Peter de Bruijn built the Mini-Mute — a clever circuit that let him mute his TV with a simple ...

This effectively regenerates the carrier signal that the IR receiver module had removed. Finished circuit on prototype board The output is then fed into a transistor configured as an emitter-follower ...
