Hey all,
Just a quick one before I sleep on my problem. I've built up my first prototype board and it's all working - kind of.
I've made a bomb prop and used the Keypad library to interface with my matrix keypad, and it all works perfectly on my Uno, but when I try run it on my board it seems to think the # key is held down (which then kicks the program into the config mode).
I've managed to trace this down to something in the basics of the chip setup, as I've managed to get it running fine by connecting the Uno pins to the board through the chip headers. I also double checked the traces and they all appear to connect only to what they should.
Any hints as to what else I should check for? And as always thanks for the help 
And I'm happy to add the code/schematics if they'll help, but I'm not sure as it's working fine on the Uno (gotta be my fault)
