PIC Tutorial - Matrix LED Board
Matrix LED Board
This is
the Matrix LED Board, a board containing an
8x8 matrix of 64 LED's, although it's a simple board,
it's by far the largest tutorial board yet. I know there are various people
who make PCB versions of the tutorial boards, and this would be a good
one for a PCB, which could be a LOT smaller.
The
board requires connecting to two complete 8 bit ports, one of which is used
to SINK the LED current, and the other which is used to SOURCE the LED
current. For this reason it's designed to use ports B and C on the 16F876 or
16F877 boards. Notice that this board requires no power, and on both
connectors neither 0V or 5V actually feed anywhere.

64 LED's, eight
resistors, and two 10 way Molex connectors. There are
64 wire links, and 80 track cuts. |
