Arduino based cellular automata

Arduino cellular automata

You have probably heard of Game of Life. It is popular cellular automata simulation game where you create simple structures in infinite plain and watch the life evolve. All this is achieved by implementing several basic rules. By implementing different rules, you can simulate biological processes, model structure behavior and program robot swarms. Building cellular automata is fairly simple. You can start with Arduino Nano and 128×64 OLED to get pretty interesting results. In this following project the Game of Life has been implemented. There are only two rules applied to pixels to make it work: A cell which is dead and is surrounded by exactly 3 alive cells, will be born A cell which is alive and has either 3 or 2 alive cells will remain alive, else it… Continue reading

Another digital clock displays Game of Life

Matthew wanted to makes geeky gift for his brother who is mathematician and programmer. So he came out with digital clock idea which would display time and play Game of Life. There are plenty of Game of Life clocks around the internet bu all seemed somewhat limited in display size. So he grabbed 16×32 RGB LED matrix and built pretty slick looking clock. The clock is build around Arduino UNO which reads time from Chronodot RTC. Clocks display is refreshed every minute and game of life start over where time digits act as initial condition. Likewise other clocks, this one always displays time in background, so anytime you could tell the time. Again – Arduino UNO has limited RAM so there has to be various optimizations and workaround made. Other… Continue reading

Conway’s game of Life on 4×20 character LCD

Duality have finished his project where he squeezed Game of Life in to 20×4 character LCD. We used to see such games on graphical LCD where cells can be represented as pixels. Here on char LCD cells are represented as custom characters. So not many of them are visible on screen. But it works fine and you can track the evolutions normally. Project is based on Arduino Uno using custom expander to connect LCD. The rest is code which is really nicely written and commented. Continue reading
