This Project Multi-Pattern Running light is used to generate several designs of Running Lights. We use ten LEDs for display. The designs can be selected by using two switches UP and DOWN. The 8 bit Microcontroller is used to control all the operations. It control the LEDs though the Ports. The above system is monitored and controlled by the 8 bit microcontroller AT89C2051. The Microcontroller continuously monitors the Switches and switch on/off the LEDs according to the Program. The Power for the circuit is derived from the Step down transformer and the 5V regulator IC7805. The regulator IC produces a constant 5v output.
