Introduction

The gator:color is one of a series of gator-clippable boards called gator:boards that SparkFun has created to interface with the micro:bit and gator:bit v2 expansion for micro:bit. The gator:color has a smattering of a different color LEDs that can be used either in place or broken away from the main board. In this hookup guide we'll go over how to light up our LEDs, both by simply turning them on and also by dimming them using a process called Pulse Width Modulation (PWM).

Required Materials

For this activity, you'll of course need a micro:bit. You'll also need some alligator clips to connect everything together, and a micro usb cable to program your micro:bit. All of these things are shown below, so grab them if you haven't already. You can go ahead and grab a gator:bit v2 as well to create some more robust projects, but you'll be able to get along fine with just a micro:bit.
