The Adafruit CRICKIT for micro:bit is a very nifty add-on. With it, you can extend the capabilities of the micro:bit to include additional inputs/outputs, capacitive touch input, servo control and DC motor control.

These functions can be accessed via the Arduino IDE with the following tutorials:

This guide presents using CRICKIT functions via MicroPython. MicroPython was started by author Damien George to allow Python programming on microcontrollers like the micro:bit. CircuitPython is a fork of MicroPython that Adafruit started to make Python on microcontrollers easier for beginners. Unfortunately, CircuitPython will not fit onto the limited memory of the micro:bit. 

There are significant differences between MicroPython and CircuitPython. This tutorial focuses on using MicroPython on micro:bit with an Adafruit CRICKIT robotics controller attached.

Sometimes we wonder if robotics engineers ever watch movies. If they did, they'd know that making robots into servants always ends up in a robot rebellion. Why even go down that...
