Conway’s game of life on arduino
- 1. Conway’s game of life on Arduino A 48x32 led matrix controlled by an Arduino able to project output from arbitrary sources (e.g. game of life)
- 2. Goal To make a led matrix on which Conway’s game of life can run And enable it to display other stuff, like Ticker tape Clock Temperature Menu navigation?
- 3. Conway’s game of life World is a grid(x, y) Each cell is alive or dead Each iteration for each cell = grid(x, y): If cell is alive, It dies from loneliness if it has < 3 alive neighbors It dies from food shortage if it has > 4 alive neighbors It stays alive if it has 3 alive neighbors If cell is dead, It reincarnates if it has exactly 3 alive neighbors
- 4. Setup Arduino 3 Led matrices (3 x 4x2(8x8), incl 2 controllers) Breadboard Wires, some resistors, leds and buttons For fun Thermometer Clock
- 6. ARDUINO SPECS Microcontroller: ATmega2560 Flash memory: 256 kB (of which 8 kB is used by bootloader) SRAM: 8 kB EEPROM: 4 kB Clock speed: 16 MHz
