IR Detector

Step 4 The Schematic

OK, first I will give you the schematic and then I will explain it.

Isn't 9 volts a little too much for LEDs even if you have a 330 ohm resistor? Unless the ir transistor provides a lot of resistance.

[Goodhart]

It depends on the amperage rating of the source, the voltage drop across the LED, and the amperage rating of the LED.

wat stops it from sensing other light sources, why deos it only detect IR

[geniustaha]

Most of the time, the surface of LED is made such that it filters out visible light and detects only INFRA RED

I made one of these years ago when i was reparing VCRs. I put it all into a atari 2600 game cartage case and the remote head fits just right in the frount to test.

Nice! Do you have some pics of it? :)

[vader0ne]

I will have to find it ,baried somewere on my desk who knows, but when i do I will take some pictires of it as a whole and apart.
