A simple arduino signal generator

Thanks ITead :slight_smile: I will try to build it, im new to Arduino and im not verry good with programing, the hardware part is not a problem for me but i have some isues with the darn libraries, and for instance in your code for this where do you define the outputs I see in the schematic you are using the Digital output pins D0 -D7 and D12, but in the code this is not set.
