I have been teaching multiple physical computing workshops at designskolen Kolding. Each workshop lasted for 3 weeks and with approx. 40 students per session. In the first workshop, the focus was primarily on learning to code and an introduction to electronics and sensors. The second time around, we moved away from the code a bit and had more fun taking apart electronic objects and then conveying new interactions using the components we dug out. Sketching interactions using old garbage is just one of my absolute favorite ways of working.
