Caterpillar Car Micro:bit Makecode Javascript: Remote Control (Discover! How? Book 30)

A tracked robot you can steer yourself makes a lively introduction to physical computing. This micro:bit project book shows how a caterpillar-track car and its remote control come together, pairing MakeCode JavaScript with motors, wireless communication, and onboard sensors.

The project also brings several electronic components into one working build: readers encounter the car’s drive system, an ultrasonic distance sensor, an LCD, a servo motor, and NeoPixel lighting. The result is a practical look at how code can coordinate hardware rather than simply run on screen. 💻

Build the car, then explore its systems

The book begins with an overview of the vehicle and remote, followed by parts and circuit diagrams. Its software material is organized into focused sections, including the main program, motor control, wireless and serial communication, timer functions, LCD output, distance detection, servo movement, and NeoPixel control.

That organization helps make a multi-part robotics build easier to follow: each system has a place in the larger program, from sending commands to moving the tracks and responding to sensor input.

Remote control meets obstacle sensing

The featured car is designed to be driven with a separate remote control, while an ultrasonic sensor is included for detecting nearby obstacles. Readers interested in robotics can see how movement, wireless commands, and sensing fit together in a single project.

A smaller micro:bit project, too

An appendix introduces a kitchen timer made with the micro:bit alone. It offers a second, more compact example of programming the board, alongside the larger car build.

For makers curious about coding and electronics

This volume will interest micro:bit users, coding learners, and hands-on makers drawn to small robots and electronic projects. Its combination of diagrams, hardware sections, and program breakdowns gives readers a concrete project to study as they explore MakeCode JavaScript and connected components. ✨
