STOP:bit for Mico:bit

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. 

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.
