This document provides information about a workshop on FIO (Funnel I/O), which is a hardware and software platform that allows physical computing using Arduino, XBee radio modules, and the Funnel programming environment. The workshop agenda includes primers on Arduino, XBee radios, and using the Funnel visual programming interface. Participants will learn how to connect Arduino-based sensors and actuators over XBee radios and control them remotely from a PC using Funnel. The document lists the required materials and provides code examples for basic input/output tasks with FIO.
