Anybody know anything about Arduino programming & IR control able to help me ?

Hello,

I'm currently building a non audio related project that uses an Arduino UNO to control a stepper motor & sync a DLSR to stck macro photographs.

The project uses an IR remote to control the functions on the Arduino.  I'm having issues getting full functionality out of the remote.

The part of the code forthe remote mapping is below.  I'm using a generic control set to Sony Bravia.  However it doesn't hve the fast forward rewind buttons.  I'm trying to map some of the other unused buttons.        I can run another bit of code that displays the numbers squirted out by the reote in decimal format.  However if I substitute them into the code below I get no response on those buttons.    Also the numeric keys get the Arduino respnding, but the numbers that the remote puts out are different to the defined numbers in the code below.  For example see the remote map below.  The defined number for key one is 16 & when I decode the remote the number being squirted out is 544993039.    Can anyone explain this ?  I've looked on teh Arduino forum etc, but I'm finding this quite confusing.

The first thing I'd confirm is that the processor's clock frequency is set to the value expected by the code.

Also, it helps to look at the output of the IR receiver on an oscilloscope, to verify that the remote is sending pulses in the format you expect.

Thanks Andy,

I managed to get this going last night with a bit of trial & error, & a wing & a prayer....  I ended up having to change the remote, although the one I was using was sending n
