ex 4.1 let there be lightex 4.2 you are in controlex 4.3 digital controlex 4.9 lcd screenex 4.7 photoresistorsex final project traffic lightex final project traffic light:
It's basically a traffic light, with a code and circuit, i set up a timer and delay for the 3 LED lights. There's 20 seconds for the green light, 15 for the red one, and 6 seconds for the yellow one. At first, I thought everything was working, but only the red LED would work, it took me 15 minutes to realize the other lights were reversed and that's why it wasn't working. To improve the project i would add a 3d printed car with a gear just to make it roll.
