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.

BBC micro:bit Go Bundle: Designed specifically for kids and beginners, the micro:bit is a pocket-sized computer that you can code, customize and control to bring your digital ideas, games and apps to life. It’s a small, code-able device that is a non-intimidating introduction to programming and making – switch on, program it to do something fun – wear it, customize it, develop new ideas. Read more.


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
