Hey, everyone! I just wanted to tell you all about Grover Mods. Mods are little widgets that you can add to give Grover even more functionality. They are meant to attach the the rail on Grover that we call the mohawk, and connect via the 6 pins on the back. Two 5v, two ground, and two analog/digital I/O pins. You can add a knob(potentiometer), a button, another led, PIR sensor and servo motor. Really anything you can think of.
