Crank Counter with micro:bit

Keep track of how many times you’ve turned that crank…

I’ve got a new guide up in Brown Dog Gadgets Project Database. This time we’re using the micro:bit along with a 7 Segment Display and a LEGO-based crank circuit. I call it the Crank Counter.

We create these (free) resources in the hopes that viewers like you support our efforts by purchasing components from Brown Dog Gadgets because hey, that keeps the free resources flowing. Thank you for your support!

Typically the build guides are not a step-by-step LEGO building guide, but they don’t need to be. LEGO should be open-ended building, and we want to encourage that. Even the circuit layout with Maker Tape doesn’t need to be precise. The components must be connected properly, but where you place them, length of tape used, etc. is less important. Building a functioning circuit is the goal. (Things that need to be more “exact” like the crank connections, are called out.)

I typically try to explain the code a bit and cover a few other basic concepts that relate to the project. Some are more advanced than others, but we try to simplify and not overwhelm.

Oh, you might be wondering if we can made a version of this that counts down as well as up depending on the direction you turn the crank, and yes, that’s possible, and it’s in the works. :)
