PeterH:
Dunno - your code looks similar to the examples. Did you notice this comment in the readme?NOTE: The code will NOW ONLY WORK WITH THE PCB DESIGN
NOT THE PROTOBOARD DESIGN.If you haven't already checked it, I suggest you focus on the hardware design to make sure your circuit is correct for this version of the library.
Thanks, But can u tell me difference with PCB and PROTOBOARD DESIGN
