The BitCar is a micro:bit-powered robot car kit featuring autonomous line following, ultrasonic obstacle avoidance, and remote control capabilities. Built around a sturdy chassis with two metal gear motors, the car includes built-in modules for buzzer, line follower, and four addressable RGB LEDs — ready to program straight out of the box.
Two spare Grove connection ports on the underside (one I²C, plus P1 and P2) allow advanced users to add sensors and modules for extended functionality. Program the car using Microsoft MakeCode's drag-and-drop block editor or text-based JavaScript. A micro:bit board is required but not included.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- Grove
- Grove is a plug-in connector ecosystem for sensors and modules that avoids soldering and jumper wires. Grove compatibility matters because it can make it quicker to add supported I2C devices, as long as the cable and voltage are suitable.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
