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 (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- 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 (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
