An improved micro:bit CPU

In a previous project I made a simulation of a very simple microprocessor using a BBC micro:bit. It’s coded in MakeCode blocks and, although it only has 4 instructions in its very reduced instruction set, it behaves in many ways … Continue reading

Make your own processor with a micro:bit

Last week I made a binary adding machine out of 3 micro:bits to learn a bit about how computers work deep inside. This week I’ve been inspired by Ben Eater’s 8-bit computer project. I highly recommend his videos if you … Continue reading

micro:bit binary adding machine

I’m going to how to show you to turn two or more micro:bits in to a binary adding machine, using the same code on every micro:bit. The ability to add two numbers together is a fundamental building block of any … Continue reading

Ultrasonic distance sensor micro:bit theremin

I’ve tried to make really crude theremin-like noise-making machines before with an Arduino and an LED, and with micro:bits, and of course there’s my spooky bat theremin Scratch project. I had a HC-SR04 ultrasonic distance sensor lying around. You can … Continue reading
