Hi,
I'm having trouble making an ir transmitter/reciever circuit. It is meant to be a parking sensor. Here are the diagrams I am using:
Parking sensor circuit

I made this circuit on a breadboard, and I'll upload the pictures later when I get home. My problem though was that the 555 timer immediately heated up, indicating something was wrong. One thing that I did do different was that my R3 in the transmitter circuit was 100ohms instead of 33ohms, as we don't have any 33ohm resisitors.
The emitter and reciever im using are from here: **broken link removed**
I made sure to point the emitter right at the reciever. But still no luck. If any more information just ask. Hopefully someone knows where I've gone wrong..
