I created Traffic Lights with Arduino and a segment display. I used one 7 segment display to count down from 9 to 0 seconds. This project is suitable for school or college students to showcase their abilities.
It is easily achievable, and I encourage people to explore it and use two displays for more output options.
If you liked this project, please leave feedback for my YouTube channel. Your suggestions are welcome for further improvement!
