I've got this idea in my head to make an 8x8 LED Grid (64 LEDs total) controlled by two PIC12F629s. One PIC is for column strobing, the other for row strobing. The ROW PIC will communicate with the COL PIC to tell it when to start strobing and what data to write during the strobing. But - 64 LEDs, 16 transistors, 25 resistors, and a big chuck of perf board is required. Plus some fancy programming. This project will have to wait until I find a reliable and reasonably priced parts supply house in the Manila area.
