ASCII-Art Arduino pinouts

Managing arduino projects can be a nightmare because you only see the software side in your code documentation, the hardware is hard to keep track off. To enable easy documentation of pin assignments, I created a couple of ASCII art arduinos; complete with ports, PWM and coms all marked. Simply paste as a comment into your code and marvel at your new found organisation. I suggest altering the image (eg. a letter or X in the [ ]) to keep track of the pins you ended up using.”
