Hi techies,

I'm trying to learn from a PNA4601M connected to arduino.
I've tried several programs, but the thing is:
When I don't send any infrared signal, the receiver still sends data towards arduino like this with the Raw IR commander:

Ready to decode IR!
Heard 3-pulse long IR signal
Heard 1-pulse long IR signal
Heard 1-pulse long IR signal

All this without ever send anything to the receiver. Is it broke?
Also when i hook up a led at the output of the ir it flashes without me sending ir.

I've also tried IRanalyzer.pde, which gave me something like this when I send ir:
Analyze IR Remote
Bit stream detected!
0      0
280      0
280      1
198728      1
198728      0
198832      0
198832      1
19788      1
19788      0
19860      0
19860      1
248744      1
248744      0
248844      0
248844      1
192004      1
192004      0

But I'm not sure how I can translate this to hex, and create an action to it.
Could also someone send me to the right direction to buy a new type of receiver? I'm thinking of: GP1UX511QS. Would this do?

Make sure your receiver is wired correctly.  You can't just attach it directly, you have to wire it with some capacitors and resistors.  Look at the schematic for this receiver board: http://www.sparkfun.com/commerce/product_info.php?products_id=8554  I bought that receiver board and it works fine, you can just stick the wires into it without making any circuitry yourself.  
I also use this library with it: http://www.arcfn.com/2009/08/multi-protocol-infrared-remote-library.html


It looks like this one on the photo:

I only have read you should put a resistor between the output of the ir and arduino data line.
Or am I wrong?
