Arduino overview

The open-source Arduino environment makes it easy to write code and upload it to the I/O board. It runs on Windows, OS X, and Linux. The environment is written in Java and based on Processing, avr-gcc, and other open-source software.

Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.

1.7.6

Version: 1.7.6

Something is wrong here. MacUpdate is showing 1.7.6 as the latest version but the Arduino/Genuino website (https://www.arduino.cc/en/Main/Software) still shows 1.6.5 as being the latest. It looks like MacUpdate has gotten the version number from Arduino srl (the company that used to make the boards for Arduino.cc). They claimed the Arduino trademark in Italy and forked the software to form Arduino.org and compete with Arduino.cc. Go to the Arduino.cc site to find the latest version.
