I have a IR detector as per the picture below, I have installed the IR library and hook it up like this :-
IR facing front :- pin 1 - Pin 11 on Arduino ( orange ) pin 2 - Gnd ( white ) pin 3 - 220R --- 5V ( red )
When I uploaded the IRRecvDemo example, nothing came out of the serial output.
I tried all combinations, still the same results...
Another thing I notice is that if I do NOT put a resistors ( 220R) between the 5V to the pin 3, in my case, the whole IR detector unit becomes very very HOT (short circuit, I guess)..
Any suggestions on how to troubleshoot this issue ?
