How can Arduino be useful in the Classroom?

• Students can easily
• read sensors and control actuators
• write programs to run on the Arduino board
• communicate between Arduino program and computer
  programs (Processing, Labview).
• control devices with larger power supplies
• communicate with the internet

12
Where can Arduino fit into curriculum

• Extensions to beginning Electronics
• Project for an technology class (EbD, Project
  Lead the Way).
• Activity in a (physical) programming class
• Student designed experiment in Physics
• Training for a robotics team
• Physics or Computer Club

13

Physical Computing by Tom Igoe

• Book Description
• ISBN-10 159200346X ISBN-13 978-1592003464
  Publication Date May 28, 2004 Edition 1st
• Physical computing is all around us-from
  interactive displays at museums to "puff sensors"
  that aid the physically challenged. With a
  multiple book buying audience, this book doesn't
  require a specific background or technical
  experience. It is designed to help make a more
  interesting connection between the physical world
  and the computer world. The audience size is
  comparable to that of the Robot builder market.
  In addition to this audience, physical computing
  is also taught at several universities across the
  US. This book is a great source of information
  and knowledge for anyone interested in bridging
  the gap between the physical and the virtual.

Making Things Talk by Tom Igoe

• Whether you need to plug some home sensors to the
  Internet or create a device that can interact
  wirelessly with other creations, this book shows
  you exactly what you need. The projects in this
  book are powerful yet inexpensive to build.
  You'll become familiar with the Arduino open
  source electronics prototyping platform, as well
  as networking hardware such as Ethernet, Wi-Fi,
  Zigbee, and Bluetooth. Get instructions for more
  than two-dozen simple projects, and then
  customize them with your own designs.
