This week I wired my Arduino and my Breadboard to take the reading from a potentiometer or a photocell and use it to turn a Servo motor at a specific angle. Here is the video I managed to capture.
This is a video clip showing the potentiometer
controlling the Servo motor:
This is a Photocell used as the control for the Servo motor:
[...] this is what they do. [...]
You can find the tutorial here, from ITP Physical Computing Tutorial for analog in and out. The photocell in the video above is used as an analog in: http://itp.nyu.edu/physcomp/Labs/AnalogIn
and here is the link for the servo control:
