Hi
I am working on a project to send a signal when aomeone cross the door...
I used an IR led as transmitter (the transmitter circuit contain 555 IC )
and in the receiver part I used a receiver transistor and LM324
put I couldn't switch the microcontroller, i mean i didn't have any signal in the output.......
could any one help me giving me a working IR circuit.....
thank you all
