{"title":"STOP:bit - Traffic Light for BBC micro:bit","handle":"stop-bit-traffic-light-for-bbc-micro-bit","url":"/products/stop-bit-traffic-light-for-bbc-micro-bit","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.\n\nAttach 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.\n\nKey Features\n\n\nPre-Assembled – No soldering required, ready to use out of the box\n\n3× 10 mm LEDs – Red, amber, and green in a realistic traffic light layout\n\nDirect micro:bit Connection – Bolt-on or clip-on attachment\n\nCustom MakeCode Blocks – Simplified coding for younger students\n\nRadio Communication – Coordinate multiple traffic lights using micro:bit radio\n\nMicroPython Support – Demo code available for advanced users\n\n\nSpecifications\n\n\nLED Size – 10 mm diameter\n\nI/O Pins Used – P0, P1, P2\n\nDimensions – 120 × 38 × 15.6 mm\n\nPCB Thickness – 1.6 mm\n\n\nRequires\n\nBBC micro:bit (sold separately)\nUSB-A to Micro-B cable\nMakeCode Editor or MicroPython environment\n\n\nIdeal For\n\nTraffic light and pedestrian crossing coding projects\nSTEM classroom activities\nMulti-intersection traffic management simulations\n\n\nPackage Contents\n\n1× STOP:bit traffic light board (pre-assembled)\n5× M3 8 mm countersunk screws\n5× M3 hex nuts\n\n\nResources\n\nMakeCode Tutorials (Kitronik)\n","vendor":"Kitronik","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":7651,"title":"Default Title","sku":"KI-5642","price":8.72,"on_sale":false,"in_stock":true,"available_quantity":112,"option1":"Default Title"}]}
