Each of those inputs as well as the very important “Earth bar” are available in the form of what I like to call
“alligator-bait” connectors. You'll use the included alligator clip cables to clip right into the hole pairs. This will all be
made much more clear in the next section. For now, let's keep summarizing your Makey Makey.
If any key is activated with the "Earth Bar," an associated LED will light up next to the pad.
Back Side
When you flip the board over to the back side, you will notice a mini-B USB connector and POWER LED. The
connector is where you will connect the USB cable to a computer. The LED will light up when the board is
powered.
You've also got access to 12 more keys via the black female headers:
W, A, S, D, F, and G on the keyboard side
up/down/left/right mouse movement and left/right clicks on the mouse side
The bottom header has six additional ground (aka Earth) outputs.
