My Light Diagram

               This project aims to design  a  Live  traffic  system. This  project  consists  of   GSM    module , LED   display ,   LPC   2138, and   ZIG-BEE module. This   system   is   mainly applicable   for   traffic   maintaining. A    speed   governor    will be   there   in vehicle   which   is   used   to reduce   the   speed of vehicle.   A speed   limit   board   will be   placed   on the   certain area   and this system consists of GSM module, LED display and microcontroller board. Traffic police could control the speed limit showing the LED display via internet. And this   speed range will be send to all vehicles through zigbee module. With   the   help   of motor   control   we   can reduce  ...

Traffic Light 20 Chanel based on 74LSxx This view of the proposed traffic Light 20 Chane based only on family and 74LSxx IC 555 as clock source. It is a digital logic circuit. To construct the traffic light rangkaian Control requires no programming of microcontrollers. This page features a circuit that has twenty open collector outputs that turn on one at a time in a continuous sequence. The circuit make use of the family 74LSxx TTL integrated logic devices. The circuits are designed to drive light emitting diodes or low current and low voltage incandescent lamps, but can also lead to other charges of 80 milliamps. 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
