Detecting Fidget Spinner Speeds with a LDR and the micro:bit

Fun walkthrough project video below using a photoresistor and the BBC micro:bit to determine the rotations per minute for fidget spinners. The code is viewable and downloadable here.

In this episode, we learn how to make and code a speed detector using a light dependent resistor and a bbc microbit.
