Upgrading a Bobby Car raceway

Through a series of fortunate circumstances, my friend and colleague Samu came into possession of some traffic lights. Which he was very happy to prevent from being scrapped.

He used the three-coloured main lights for himself. One as a light organ, the other as a Jenkins status display (seriously!). Brilliant!

So I asked him if he was willing to give me one of the smaller ones and suddenly he agreed. Without a second thought I build a fully working traffic light for the Bobby Car raceway of our local day care centre.


It was a fun mini-project and of course I published the software and a rough schematic on GitHub: TrafficLight.
