Course synopsis

The first half of this practical project-based course is spent covering the basic technical skills (including electronics, programming, and hardware) needed to build simple interactive objects with embedded behavior using the Arduino microcontroller. Inputs to read information about the world include sensors such as an ultrasonic ranger, thermometer, light sensor, and human inputs like buttons and knobs. Outputs to affect the world include actuators such as motors, LED lights, speakers, and haptic feedback devices. Individual and group projects challenge students to apply their technical skills in creative ways. The class will be working with a local group of older people who serve as design clients for the final project; students conjure and build functioning assistive devices of a practical or whimsical nature for their critique and feedback. Readings and guest speakers address topics pertaining to design for older clients.
