The correct way to make traffic lights for a 4-way intersection.
Project showcase by stemmayhem
Hot Wheels and Lego are the exact reason I built it :)
I think you could make a mesh, either by using a single Uno, or by adding Bluetooth to this one. You could give each set of lights an id, and just detect the previous id and then sync to whatever time you want. Saying that, I am not sure how old your kids are, but mine certainly would hate an ideal traffic flow. Sounds awesome to me, but they want to stop and start at these lights, not hit a green all day long :)
Let me know if you create a network. Thanks for the comment.
Hi Dan... I am pretty new to Arduino, and I have never used the ATMega328, and I didn't know it had internal timers. That's very cool to know. Thanks for the comment!
