This is a simple Snake Game targeted at children and for hobbyist. This game is made by using Arduino.In this Snake Game Dot matrix display is used for displaying snake and food. And for score and game status like Game Start, and Game Over is displayed on 16×2 LCD. For controlling the game five push buttons are used (Start, Up, Down, Left and Right). To drive the Dot matrix display Shift registers are used. To start the game you have to press Start button and then use other Keys for direction.
Light emitting diodes aligned in a form of matrix constitute a dot matrix display. It is commonly used to display time, temperature, news updates and many more on digital billboards. Dot Matrix Display is manufactured in various dimensions like 5×7, 8×9, 128×16, 128×32 and 128×64 where the numbers represent LEDs in rows and columns, respectively.Arrangement of the LEDs in the matrix pattern is made in either of the two ways: row anode-column cathode or row cathode-column anode. In row anode-column cathode pattern, the entire row is anode while all columns serve as cathode and vice-versa pattern is there in row cathode-column anode. LED wafers are glued to the bottom of the segments and glow when powered ON. The interesting part is that 35 LEDs are controlled by using a combination of 14 pins. Conductor tracks are laid all over the board to power each LED. Let’s proceed to know in depth about how a dot matrix display works.
