Dancing Inchworms

This involved cardboard engineering, incorporating a servo motor, a twisted paper pin and controlling the inchworm with the Micro:bit.​

The first day the kids had a working prototype that inched forward "forever" when you pressed the button on the Micro:bit.  This led to the battery running out overnight since they had forgotten to disconnect.

​By the last day of camp, the kids had the engineering nailed down and also figured out how to remotely control the inchworm using a second Micro:bit and stopping the inchworm on command.  No more discharged batteries!!
