I'm working on teaching myself Arduino, and decided to make an attempt at a simple traffic light pattern that I may turn into a scale model later. Here's the first test.
Green light turn to Yellow warning indicator. The Yellow waits a few seconds, then turns to Red. Both lanes are Red for a few seconds, then the second lane turns to Green, and the pattern repeats on the other side.
Next, I'm going to see if I can add a left-turn indicator into the pattern.
