Optimizing A Servo Motor With Input

This user came up with an interesting approach to physical keyframing by reading the voltage off the center pin from his servo’s potentiometer. By doing so, he optimizes the device’s potential since it can now be used for both input and output purposes.

This way he can manually create a sequence of positions with the arms of an object that he’s animating, have this sequence recorded and then subsequently played back by his computer.

Check out the author’s page for the device’s other possible applications as well as the source code. As the author puts it; you get a bunch of extra sensors for free by following his approach.
