We will now install software to program our arduino uno. This arduino uno software is a free download and will operate on several operating systems. The IDE (Integrated Development Environment) software uses a streamlined version of C++ to write and upload code to the boards. This software is open-sourced and available free of charge. It will run on Windows, Mac, or Linux.
We will be installing the Arduino IDE on a Windows 7 machine. Connecting to our Arduino Uno, we will modify the blink program. (sketch) Let’s get started.
