micro:bit Rover Lessons - Lesson 1: Designing M3 Bolt Test Pieces

This is the first of a series of lessons where students will build a robotic rover using the BBC micro:bit. In this lesson, students will determine the proper diameter for M3 bolts by making test pieces with different diameters. Students will use the engineering design process to find a diameter that can be used for M3 nuts in the other lessons in the series.
