Angle Sensor for Vex

[Noggin]

Just wanted a wide enough range to determine when the arm was all the way down, all the way up, and an idea of where its at in the middle. I want to control an articulated arm to determine position upon bot startup and set both arms to their neutral positions, then use the sensors to detect extension and make sure the upper arm is limited while the lower arm is in its neutral position, and make sure the lower arm cannot close if the upper arm is beyond a certain point. I was thinking of using the pots connected to chain drives to do gear reduction to get a analog input for the entire range of motion along both arms.
