An early prototype, with the controller app
The final product
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 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%.
