Two months ago I used to live off-campus near Penn State’s main University Park campus. My apartment was full of art students, with myself being the only non-art student. I decided to combine my knowledge with my roommate’s\u00c2\u00a0experience\u00c2\u00a0to create a real-time demo project using an Arduino and Gameduino. In essence my goal was to make something similar to a demo (read more via Wikipedia)<\/a>\u00c2\u00a0fulfilling the requirements of: a unique graphics output, all computed at real-time, using only the Arduino processor and the Gameduino<\/a> VGA output of 400×300 pixels. This project was quite a challenge as I was using an Arduino Uno which comes with one\u00c2\u00a0ATmega328: 16Mhz\u00c2\u00a0embedded\u00c2\u00a0processor with 2KB ram and 32KB programming memory!<\/p>\n

Here is my result, recorded via camera (sorry, I had no in-line recording system for a VGA cable) and uploaded to YouTube. The demo lasts just short of two minutes. The final code compiles to about\u00c2\u00a027218 Bytes (~26KB) and includes a dozen effects: plasma, nyan cats, fun spirals, 3D cubes, pseudo\u00c2\u00a0cellular automaton, and a Portal 2 reference.<\/p>\n

Just to make things clear: this entire video was generated by an Arduino and Gameduino connected via VGA to a standard TV screen; nothing was precomputed or loaded upon run-time, everything you see is done real time.\u00c2\u00a0<\/strong><\/p>\n
