Kitronik STOP:bit Traffic Light Board for micro:bit Educational Kit

The Kitronik STOP:bit Traffic Light Board is a pre-assembled traffic light project for the BBC micro:bit, standing 120 mm tall and designed for beginners and classroom use.

Overview

The STOP:bit allows learners to build a functional pedestrian crossing simulation without soldering or complex wiring. Three 10 mm LEDs in red, amber and green are connected to the micro:bit's P0, P1 and P2 pins, so each light can be controlled directly through simple code. The micro:bit attaches securely to the board using the included M3 screws and nuts, forming an integrated unit. Power for the LEDs is drawn from the micro:bit's connections, which simplifies setup.

Key Educational Features

Kitronik provides custom MakeCode blocks that make programming the traffic light sequence intuitive and accessible, including for younger students. The project supports teaching core programming concepts such as sequences, loops and conditional logic in a tangible context.

Design and Expandability

A snap-off base section forms a cross-stand, allowing the traffic light to be displayed prominently. For more advanced projects, multiple STOP:bit kits can be combined and synchronised using the micro:bit's built-in radio module, enabling coordinated, multi-light systems for larger-scale simulations.
