What is RAGen?
RAGen is a software application that will let you generate code with just simple click of your mouse. No programming experience required. RAGen is a contribution by Curt Binder.
The first thing we need to do is get all the necessary software installed in your computer.
Let's start with the Reef Angel Installer:

This installer will install the Arduino IDE, drivers and standard libraries.
Then, we need to download the RAGen application:

After you have Reef Angel Installer and the RAGen application installed in your computer, you are ready to start generating codes.
Let's do it once for you to see how it is easy.
Your very first generated code will be the initial memory settings that the RAGen application will assume you have. This is only necessary to do it once and never again. So, let's just generate and upload it now and you won't need to worry about this step again.

We are all set to start generating customized codes.
Let's do a quick one:

As you can see, it is very simple and easy to generate your own customized code for your Reef Angel Controller.
