infrared remote tester circuit diagram

This is an infrared remote control tester circuit which gives both an audio and visual indication that a remote controller is functioning. D1 is a reverse biased photodiode which forms an IR detector.

It’s output is buffered by IC1a and then enters a pulse stretcher comprising C2, R2 and IC1b.
The pulse stretcher enables even the shortest of pulse trains to trigger the following oscilator. D3 is a low current red LED which provides the visual indication when the infrared remote is directed to the tester circuit.
