Square LED matrices that look 'round (with apologies to Roald Dahl).
I wanted to do a project to start hacking on AVRs and multiplexing LEDs. So, here's what I came up with.
Originally, my plan was to mount the eyes on a pumpkin and cover it with a fabric mask. Instead, I'm thinking of putting it in a small cigar-like box with the same black fabric and prop the box top open as if the creepy crawly is looking out.
Hardware list (major parts):
- Atmel ATMega168 AVR
- 2 Maxim MAX7219 Display Drivers
- 2 Luckylight 3mm 8x8 Dot Matrix LED Displays
