Circuit Play emphasizes free play and kinesthetic learning to introduce circuits and conductivity. The set of puzzle pieces, wrapped in copper foil and attached to an Arduino, uses capacitive touch sensors to build out a form that can move and light up by human touch. Puzzle pieces fit together by slots and allow for infinite formations and more complex interactions. Human touch powers the Arduino pieces, turning on LEDs and servo motors. The project is intended for an educational experience that is explorative and open, allowing kids to learn through experimentation.



The process for making was itself experimental with explorations in capacitive touch sensors and their possibilities. Puzzle pieces were made with laser cut plywood and acrylic and wrapped with copper foil tape, then attached with jumper wires to Arduino Unos.
