he is using a bare 328, he soldered a pcb up. But I'm using an Arduino Uno. I have a diagram of the 328 and uno so I should be able to to translate the pins. Eventually when I come to build this I will need the things on the left. Because its a midi loop pedal with a screen in it. I will have a go now to redraw it as a schematic and see what it does. I will upload it along with the Arduino program
