This project simulates the operation of a traffic light that is actually used to regulate traffic in everyday life. Three diodes are used that alternately light red-yellow-green-yellow-red, which are controlled by a program and turn on and off. There is also a connected 7-segment display with a common cathode that counts down the remaining time of the red and green diodes. The red and green diodes light up for 10 seconds each, and the yellow one for two seconds.
