16 Led Chaser

            The heart of the project is Microchip Pic 16F628A. The Pic 16F628A muc can show various type of led design. You can seen in the above video.The 8 O\P of muc drives the 16 leds. The push button help to change the led pattern.

My POV Display

         My name on the POV display.....................

                              Everywhere the name is in the matrix display. But i  think why should my name in POV. So i build the POV. Pic 16f84a is the heart of the project. The name in the POV can change every time without connecting the PC.

Pic 16f84a Led cube

                      Here is my 3x3x3 LED Cube project. It runs using a PIC16F84A. Each layer of 9 LEDS are connected with all of the cathodes together. The cube is multiplexed, means that only one layer is on at any one time. It happens so quickly so the whole cube looks like it is illuminated.
