Pressure Plate Sensor Prototypes

5th graders have hand-coded their Stopwatch programs in Scratch, and now it’s time to build pressure-plate sensors that can activate their timers during a Track-and-Field race. Students are prototyping with MakeyMakey‘s, cardboard, wire, tinfoil, tape, and MakeDo connectors. Some early testing successes and failures are leading to new questions. Go engineers, go!

EdCampNYC

Jaymes Dec and I hosted a session at EdCampNYC where folks created a physical/digital chain reaction with WeDo and Scratch. (based on Amos Blanton & Eric Rosenbaum’s post from ScratchEd)
