## Description

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. Key Features Pre-Assembled – No soldering required, ready to use out of the box 3× 10 mm LEDs – Red, amber, and green in a realistic traffic light layout Direct micro:bit Connection – Bolt-on or clip-on attachment Custom MakeCode Blocks – Simplified coding for younger students Radio Communication – Coordinate multiple traffic lights using micro:bit radio MicroPython Support – Demo code available for advanced users Specifications LED Size – 10 mm diameter I/O Pins Used – P0, P1, P2 Dimensions – 120 × 38 × 15.6 mm PCB Thickness – 1.6 mm Requires BBC micro:bit (sold separately) USB-A to Micro-B cable MakeCode Editor or MicroPython environment Ideal For Traffic light and pedestrian crossing coding projects STEM classroom activities Multi-intersection traffic management simulations Package Contents 1× STOP:bit traffic light board (pre-assembled) 5× M3 8 mm countersunk screws 5× M3 hex nuts Resources MakeCode Tutorials (Kitronik)
