The Kitronik STOP:bit is a pre-assembled traffic light board designed for the BBC micro:bit. It replicates a real traffic light with three 10 mm LEDs (red, amber, green) driven directly from the micro:bit's I/O pins (P0, P1, P2), making it ideal for pedestrian crossing and traffic management coding projects.
Attach the micro:bit directly to the STOP:bit using the included screws, or connect with crocodile clips. Custom MakeCode blocks are available — search "Kitronik" in the MakeCode Editor's "Add Package" menu and select "kitronik-stopbit". Multiple STOP:bits can communicate via the micro:bit's radio module for multi-intersection traffic management scenarios.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- MicroPython
- A version of the Python programming language made to run on microcontrollers. It matters because it lets beginners write readable code to control LEDs, sensors, motors and displays without needing to start with lower-level languages.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
