Books and Manuals

Getting Started With Arduino (by Massimo Banzi): It's a guide for absolute beginners that takes you through the basic steps of learning how to use Arduino.

Making Things Talk (by Tom Igoe): teaches you how to get your creations to communicate with one another by forming networks of smart devices that carry on conversations with you and your environment.

Learn electronics using Arduino: an introduction to programming, input / output, communication, etc. using Arduino. By ladyada.

• Lesson 0: Pre-flight check...Is your Arduino and computer ready?
• Lesson 1: The "Hello World!" of electronics, a simple blinking light
• Lesson 2: Sketches, variables, procedures and hacking code
• Lesson 3: Breadboards, resistors and LEDs, schematics, and basic RGB color-mixing
• Lesson 4: The serial library and binary data - getting chatty with Arduino and crunching numbers
• Lesson 5: Buttons & switches, digital inputs, pull-up and pull-down resistors, if/if-else statements, debouncing and your first contract product design.

Arduino 101 videos from Make (part of the How-To-Tuesday series):

• more...

Tom Igoe's Physical Computing Site: lots of information on electronics, microcontrollers, sensors, actuators, books, etc.

Example labs from ITP

Spooky Arduino: Longer presentation-format documents introducing Arduino from a Halloween hacking class taught by TodBot:

• class 1 (getting started)
• class 2 (input and sensors)
• class 3 (communication, servos, and pwm)
• class 4 (piezo sound & sensors, arduino+processing, stand-alone operation)

Bionic Arduino: another Arduino class from TodBot, this one focusing on physical sensing and making motion.

Fritzing: an open source electronic circuit diagramming tool designed for users not previously familiar with electronic schematic diagrams.

Schematics to circuits: from Wiring, a guide to transforming circuit diagrams into physical circuits.
