Microcontrollers Part 4
OK!
I was able to program / animate the LED matrix. Basically, there are 8 pins on each axis, and you scan down one column at a time shifting bits out to off/on states for each LED in the row.
Each LED is only light 1/8th of the time so I need to boost the brightness a bit, see if I can lower the resistors maybe.
Now that I have it working I can get it all permanently soldered into place, and then work on the sensor components.
And of course, come out with some nicer animated faces :)
