This video describes how a Micro:bit can control both rotation and speed of a regular motor. Along the way, both voltage sharing and transistors are studied. The experimental set-up is built on a wooden board, but can also be made on a breadboard. In addition to wood, brass nails, mounting wire, solder and tools, you must use:
A Micro:bit with batteries, a small motor, test cables, 5 pcs. 2.2 kΩ resistors, 1 pc. 3.3 kΩ resistor, 3 pcs. BC 547 or other NPN transistor, 2 pcs. BC 557 or other PNP transistor.
