A small, toy-sized car that uses a BBC micro:bit, and is controlled using a smartphone


We designed a PCB that uses a H-bridge made up of transistors. This allowed us to control the direction of current flow, which determined which way the motors would spin.


The micro:bit was programmed using JavaScript, and responded to inputs from the open source app micro:bit blue, using the Bluetooth feature of the micro:bit.


The base of the car is a laser-cut sheet of acrylic plastic. The car is held up by two wheels, and a ball caster to keep balance.


This project was part of our university course, and received a grade of 90%.
