I've seen "Bad Apple!!" video (http://www.youtube.com/watch?v=G3C-VevI36s) and the wonderful stop motion version (http://www.youtube.com/watch?v=240Vq6tIxio), and I wanted to make my own really small tribute with my really small Arduino and my really small led matrix ! ;-)
Here is the result, pretty simple. http://www.youtube.com/watch?v=4UcelNOeJFU
On Arduino : led matrix initialisation, waiting for incoming data over serial port and sending them on the display. I can't do easier ! Next version will be with SD card and 30fps synchronisation.
On the computer : video resize (24x16), black&white, conversion to the led matrix display format. Music was added after the shoot, over the video.
Have fun with Arduino ! ;-) Frederic, Strasbourg, France
