Microcontrollers Part 4
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 :)

Microcontrollers Part 3
I've got the LEDs for the eyes in and programmable, and have the face matrix assembled but that's not yet programmed. It will eventually be hooked up to sensors to react to the environment as well.
So far this weekend I've spent a lot of time relearning C and especially pointers. Matrix and timings for the rest of the animations will be challenging, too. Trying to fit everything in a few Kb of space brings me back.
Watching myself on video makes me realize I really need to work on my um's. :(
Here's a video of what it should end up looking like, although mine won't look so polished:

Microcontrollers Part II
Nothing special, but it is flashy and blinky so I made a video of it working.

Soldering is a lot of fun, it turns out.
Now, the little switch on top of that board I can read from inside of programs on my computer, like so:
Not bad for a first little project.
I'm going to construct some camera triggers, so that I can take pictures from sensors like motion, heat, laser, etc.
