Micro:Bit Remote Control Car

• 

  An early prototype, with the controller app

• 

  The final product

Overview

A small, toy-sized car that uses a BBC Micro:Bit, and is controlled by a smartphone app using Bluetooth.

Hardware

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.

Software

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

Chassis

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

Grading

This project was part of the 'Engineering Projects and Entrepreneurship' module of our degree programme, and received a grade of 90%.
