Mirror management system

Here's a short, badly narrated video of the new mirror management system that Wayne & I have built. He designed a circuit that uses an IR LED in conjunction with an opto-transistor to detect the position of the mirror. This feeds a 0 to 5V DC signal to the Arduino. The Arduino then maps the analog input value to a servo position.

The green potentiometer that's connected to the Arduino controls the set-point for the mirror position. By turning the knob we can actively move the mirror itself. It's pretty cool. ... https://www.youtube.com/watch?v=QC7H61palXs
