Would someone please help me a bit by steering me in the correct =
direction here?  I've read everything I could find in books and on the =
net about this subject, but I'm still very stupid when it comes to the =
electronic bits.  Please forgive my ignorance, but I'm really trying.

I want to add distance measuring to my robot.  I connected an IR =
detector (TSOP) to a breadboard and then connected it to a PIC chip on a =
development board.  Using MPLAB and ICD2 and the development board, I =
wrote some code to detect when the IR detector detects something.  I put =
the debugger into a loop to stop when the IR detector receives something =
and it worked great.  So far so good, I thought.

To test things, I used our TV remote control.  Every time I pushed a =
button the debugger stopped at a break point.  Perfect!  Yes?

No!  No matter where I pointed the thing, the IR detector detected it.  =
I even put aluminum foil around the IR detector, and still it wouldn't =
fail.  It is just a Gr=FCndig TV and remote.

What am I doing or thinking wrong? =20

I tried to move from IR to sonar, but I cannot understand how the =
electronic portion works for the receiver. (I've ordered "The art of..." =
 and "Beboop.."; they are on their way.)

Thanks very much to the people who take the time to help me.

Cheers, Lindy
