ALL Remote Tester Circuit


This is a simple remote controller tester circuit based on infrared sensor IC TSOP 1738. TSOP 1836.etc When the IR waves fall on the sensor it output changes to low state.This makes the transistor Q1 ON and LED will blink according to the code contained in the signal. So for press of each button the LED blinks in different ways. This is a good indication of the working of remote.


Notes .
This circuit can be used to test remotes operating in the 38Khz carrier frequency.Almost all remotes fall into this category so no problem.
