IR circuits

[ah_Hui]

i'm looking for a simple IR detector.....together with a transmitter circuits..
i have 1 design which i think is quite complicated....
any 1 can show me the circuits?

am not sure of what you mean by saying you have a complicated circuit, does it mean you don't understand how the parts used do its funtion, or maybe the parts used in the circuit is not available in your place?

anyway, try this site:
http://www.discovercircuits.com

i also have those circuits, but then again it might look complicated to you :wink:

pls. be specific, don't be shy to admit if you are new to electronics, the guys here are all willing to help out :wink:

the link is not working....
anyway....what i need is just a circuit comprising an IR transmitter and detector.....once the detector detects IR light....a LED will light up....
thanks guys..
