Good stuff Alex.
All the code you will need is already written and available, I'll compile you a list of useful projects shortly.
There are a heap of simple Arduino learning projects. There should be a ton that come with the IDE from memory. Work with the "blink" sketch first, play with it to get the feel. Other examples will include relays & end-stops etc.
With a genuine intent to learn, the only stupid question is an un-asked question.
