Step 8: Decide which muscles are going to control which button(s)

Now, you're going to have to decide which muscles/muscle combos you want to use for your button(s) layout. We've opted to go with the following layout. If you want to go with a different layout, you'll have to make some modifications to the Arduino code we'll get to later on.

Function buttons:
Button A --> Right forearm muscle
Button B --> Left forearm muscle
Start Button --> Not muscle controlled
Select Button --> Not muscle controlled

Directonal pad:
Right  --> Right bicep muscle
Left --> Left bicep muscle
Up --> All four muscles (combo)
Down --> Left and right bicep muscles (combo)
