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.

The STOP:bit is a bolt-on/clip-on board for the BBC micro:bit, replicating a traffic light. The PCB has been designed to have the same physical features of a traffic light, with the addition of a BBC micro:bit as the pedestrian crossing control box. The STOP:bit has 3 10mm diameter LEDs. Each of these LEDs is driven from one of the BBC micro:bit IO pins. Power to the LEDs is supplied from the BBC micro:bit connections. STOP:bit is supplied with 4 countersunk screws which gives you the option of bolting the microbit directly onto the STOP:bit. Alternatively, crocodile clips can be used between the pads on the STOP:bit and the corresponding pads on the microbit.

If your scope is larger than a single traffic light, you can use the microbits radio module to communicate with other lights if they also have a microbit attached. This is great for exploring traffic management in a town or city.

We have also had some custom blocks added to the MakeCode Editor to make the job of coding this project much more simple. This will allow you to
