Step 8Construction: Adding power lines
Every Nintendo controller I have seen was kind enough to have a couple extra pad's and holes made connecting to power and ground, its a great place for a decoupling cap, so lets add one
Insert your 0.1uf cap into the top of the pcb, fold it over so it lays flat, and away from the screw hole in the corner, flip the board over and solder its leads to the pads, but do not clip the leads short yet
Now solder 2 jumper wires to those pads (I could have done this differently but hindsight is 20/20) for ground and + 5v, now you can clip the leads of the capacitor
Wrap the power and ground jumpers to the top of the board, connect +5v to pin 7 of the mega, and connect ground to pin22 of the atmega
