Infrared (IR) Remote Control Tester Circuit

This is a simple IR tester circuit you can build in order to test infrared remote controls. The circuit uses an IR photo-transistor (IR1) to detect a remote control’s IR output signal.

C4220µF 16V
IR1Infrared Photo-Transistor
LS18Ω 0.5W Small Speaker
IC1LM741
IC2LM386

This circuit is designed to  demodulate amplitude-modulated (AM) IR light beams will drive a speaker.

LM741 is amplified the IR1 signal and LM386 is driven the speaker.

VR1 is used to control sensitivity and VR2 is used to control the volume of speaker (LS1)

The Speaker  will sound when any of the Remote-Control pushbuttons will be pressed.

This circuit tests consumer electronic hand held remote controls such as those used by TVs, VCRs, DVD players and more.

    well we can receive signals just by tuning our radio(AM) while pressing the remotes button do we ? but it gives only simple beep beep noise ,,,coz some times i does that when ma tv s remote control get upset !!! thanks

    Thanks a lot. Made this. Works well. But AA batteries can’t give enough power and work a bit of time. Connected it to power supply. Wait for other cool stuff.
