UAF Development Progress

UAF's servo motors are still operating from a single potentiometer, and unfortunately the PIR sensors purchased seem unable to offer a readable output for the Arduino. Although the sensors could successfully be powered from a 12V source (by indication of the LED on the sensor flashing), there is no clear way to get a safe reading the Arduino could use.

It does seem, that it is only the brand chosen that seems to be the problem, as there are pieces using the Arduino and a particular PIR sensor manufactured by Parallax in the US. Unfortunately, importing these sensors is not financially feasible so a compromise must be sought in order to still offer user interaction, I am thinking that using a second potentiometer so users can control the two axis of movement separately would be a successful compromise, as it will still offer interaction and user satisfaction, but, unfortunately, the 'uncontrollable' aspect will be removed.
