The STOP:bit for the BBC micro:bit is the ultimate upgrade for traffic light/pedestrian crossing projects. Not only does it make coding the project a breeze, the board is supplied pre-assembled so you don’t even need to fire up the soldering iron. Love it or hate it, variations of the pedestrian crossing project have been around for decades. When I did mine, it was on a 6502 EMMA board and coded with Assembly and it also included a level crossing. Thankfully, tapping low level programming languages into a hexadecimal keypad is now a thing of the past. The Kitronik STOP:bit is a purpose built accessory that can only lead to a more enjoyable project with a nicer looking end result.
