We introduced a group of kids, ages 10-14, to the basics of electronic prototyping. They built moving machines and reactive toys with Arduino processors, servo motors, switches, LED lights, and various sensors. They learned how to wire electronics and how to program micro controllers. This week-long class was a collaboration between Zeum, San Francisco's children's museum, and the Gray Area Foundation for the Arts. Taught by David Dymesich and Matthew Canton, both MFA graduates from California College of the Arts.
