Now that your Makey:bit is in place, flip your monster over so you can see the back side.
Find the cable from your 180-degree servo motor and get it ready. Make sure the brown wire is on the right side.
Plug it into the three pins on the bottom left of your Makey:bit, with the brown wire still on the right.
Here’s a quick reminder:
Brown (-) goes to GND
Yellow (signal) goes to P0
Nice and neat!
