This project uses visual block programming to model events in the logic of an Australian traffic light and scale this logic to make two traffic lights work in tandem. You can do this solely in a web browser, or push your code onto a Chibi Chip and use conductive tape to incorporate this with physical models designed from a variety of mediums including 3d printing or laser cutting.
Our friends at Kitronik have made three great tutorials onprogramming the Kitronik STOP:bit Traffic Light, with yourBBC micro:bit. These tutorials are designed for students that are comfortable with drag and drop coding, usingMakeCode in the browser.
