Balanced Three phase AC circuit Delta connected

A balanced three phase AC circuit systems is energized by three equal alternating emf's of the same frequency but 120 degree apart. The phase impedance are equal. Also the currents are equal and 120 degree apart. Three AC emf's differing in time phase by 120 degree DELTA (MESH) CONNECTED SYSTEM This...

Electronics :Traffic light Circuit

This is a two way continuous traffic light circuit which uses  LED, diodes and IC's .  Usually most traffic light in the world is PLC controlled but this circuit is  simple  and easy to build .   In the image below is the schematic diagram of the project ....
