Build this Traffic Light and learn how electronic circuits control the markings. HOW IT WORKS: Traffic lights work by using a smart digital electronic system. In digital electronic systems there are only two kinds of signals, on and off. In manual mode, each time the button is pressed, an enable signal is passed to a counter circuit that counts in 2-bit binary numbers (0 and 1) from zero to three. This meter is connected to the lamps. With zero it sends a signal to the red LED.
