Arduino Traffic Light Controller for Kids Toys
Our kids love playing cars and trains, so we decided to make them a cool set of traffic lights out of cardboard and Arduino. We think these traffic lights are pretty awesome because of a few reasons:
- We didn't use the 'delay()' function as a timer.
- We included a dial to change the green light time.
- Compact design running on 6AA batteries.
- Made from recycled materials.
In our detailed post, we go into depth about how we made the traffic light controller, and explain our unique code and why we don't use the delay function. You can also download our Arduino Sketch so you can make your own traffic lights at home.

Layout of Our Arduino Traffic Lights
Here is the breadboard layout for this project. It really is quite simple. The only thing we didn't include was the on/off switch. (Sorry!) It is just an inline switch on the positive side of the battery.
