This electronic project based only on 74LSxx family and IC 555 as clock source. It's a digital logic circuit. To build Traffic Light Control you don't need microcontroller programming.This page features a circuit that has twenty open collector outputs that turn on one at a time in a continuous sequential manner. The circuit make use of the 74LSxx family of TTL integrated logic devices. The circuits are designed to drive light emitting diodes or low current, low voltage incandescent lights but can also drive other loads of up to 80 milliamps.
