Two Player Pong Game Using 5x7 Dot Matrix

Figure 1 

The project has been assembled on a breadboard to create a classic pong game where each of two players have to control the bouncer with two buttons connected to ATmega16 microcontroller.

During the game, the paddles move up/down by pressing the buttons causing the ball to bounce back and forth. The opponent will get the score if the player fails to catch the ball. The difference in score will show in blue LEDs which indicates a lead by one point. Another winning point will proclaim the winner of the game which is displayed as either player number 1 or 2.

Time multiplexing is used to drive the LED dot matrix where the columns are displayed one by one in rapid succession. This will give the illusion that they are all lit at the same time. The device illustrates a dual boot feature. One of two rightmost buttons have to be pressed when powering up the device since one of them may start the pong and the other one starts the alphabet. The alphabet can be scrolled through by pressing the buttons. This is educational in learning dot matrix control with time multiplexing.
