Shutterfingers works!

I mentioned my plans to make a servo controller to mechanically press the shutter button on a camera when signaled from a motion control timelapse robot. The parts have arrived and it’s running on a breadboard. I’ve had to make a few changes to the code, including fixing a variable reference, but the biggest change was to implement the internal pull up resisters on the Arduino and reverse the logic. That simplifies the wiring. Oh, and here’s the wiring diagram I used to help me figure out servo wiring.

What remains is to solder everything together and mount it in my aluminum project case. I’ll need to drill and tap that to mount to the tripod.
