Arduino code language: Learning to Program the Arduino

Arduino is a fusion of three critical elements: hardware, software, and community. To get the most out of it you need to have a basic understanding of all three elements, and for most people the biggest challenge of the three will be hardware. Before you jump into any of the projects please take the time to read through this chapter. Not only will it provide background information that the projects require, but it could save your life!
