Microbit truth or dare game tutorial
In this project we will be making a truth or dare game using a Microbit and a continuous servo. The game is an extension of the on-board version found on the official Microbit site. The project was designed to give non-coders the ability to make an exciting project where they could both improve their coding skills and express themselves through creative designs.
