Variable 4 way traffic light, Software to install, Project overview, Components needed, Arduino mega, Proteus simulation of variable traffic lights, Arduino code, declaration code, void loop, void setup, Results/working, Hello guys! I hope you’re all in a good mood today because we are going to review the design of an interesting project today. We’ll be looking to design 4-way traffic lights in such a way that their delay is variable and is dependent upon the traffic density. This project is of intermediate difficu ...
