Rangkaian Traffic Light 20 Chanel Berbasis 74LXX

This electronic project (Rangkaian Traffic light) based only on 74LSxx family and IC 555 as clock source. It's a digital logic circuit. To build rangkaian Traffic Light Control you don't need microcontroller programming.

notes:

• The low output go in sequence from 1 - 0 and back to 1 -0
  
• At the clock rate of the 555 timer
• c3 = 1uf to 10uf depending on the rate of change desured
• R2 (Variable resistor) in use to determine the timer

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.
