Grinding Pendulum Rotation

Building a Simple Pendulum and Measuring Motion With ...

On the front, you'll see the pendulum arm, rotating on a bearing, suspended on a rigid rod. Attached to the pendulum arm is a simple gear that rotates around the same axis as the pendulum. This gear drives an identical gear attached to a potentiometer mounted adjacent to the pendulum arm. Moving to the rear, you'll see the potentiometer wired to an Arduino mounted to the back of the L-shaped ...
