Here’s another superb Arduino project using just a few simple
components (which are available in our DIY projects store). It’s
a pretty simple setup using a laptop, webcam, servos, and an
Arduino to monitor and balance a ball bearing on a flat surface.
The ball’s position is traced via webcam and Processing. Based
on the ball’s position, the servos make corrections to move the
ball around the board. See the video above for full details. -

the rig has been built and hooked up to a laptop running the
code, the steel bearing can be placed anywhere on the board and
made to follow either pre-programmed routines or via mouse
control. The webcam tracks the ball, keeping it from falling off
the edge. Check out the full details and code.
