This diagram uses the original Gemma but you can also use the Gemma M0 with the exact same wiring!

Follow the circuit diagram to and solder the components together using wrapping wire. Carefully measure the lengths of wire to ensure the components will have enough slack to reach the desired location in the 3d Printed model. The ray gun will require significantly more wire.
