== Homework ==

Working in pairs, come up with a plan for a simple interactive object composed of a sensor, microprocessor, and actuator. The sensor will be its means of gathering information from its environment (perception?), and the actuator will be its way of responding. Acquire both the sensor and the actuator, and bring them to class next week. This means... if you need to order something online, be sure to do so before the weekend. Also try local stores: radioshack, Industrial Liquidators, San Diego Electronics Supply, or Frys.
