Arduino Development for OSX and iOS (2015)
2. Sketch Programming
This chapter explains how to work with Arduino development using Sketch.
2.1 Getting Started
The Arduino integrated development environment (IDE) is a cross-platform application written in Java, and derives from the IDE for the Processing programming language and the Wiring projects. A program or code written for Arduino is called a "sketch”.
To develop application based on Arduino board, we need Arduino software. You can obtain it on http://arduino.cc/en/Main/Software . Please install based on your platform. I recommend to install Arduino 1.6.5 or later.
Then, you execute Arduino software. In general it will detect Arduino hardware include Arduino type and model.
