Traffic Light

thingiverse

I'm a teacher who teaches Arduino programming and was looking for a simple project to explain basic programming concepts in an easy-to-understand way. A colleague suggested letting students program a traffic light, which sounded like a great idea since it's an accessible project that can be easily expanded upon. The project starts with a basic sequence of colors (red, then green, then yellow), and the next step is to connect all the traffic lights together. The goal is to create a program that detects any malfunctions by making the yellow light blink in such cases. I factored in the accuracy of my 3D printer, which has an accuracy of 0.1 mm. However, I found that the holes for the LEDs (5mm) were too small, so I used the tip of my hot soldering iron to enlarge them, and it worked perfectly well. Alternatively, you can also drill the hole to the desired width.
