Hi Frank, and welcome to the wonderful world of Arduino.
I suggest that you start off by looking through some of the code examples on this site and build up some sketches and circuits. There are a lot of good books, too, that you should buy or borrow.
I caution you from jumping in too quickly and asking the members on the forum to draw your circuits and write your code for you. The fun is in the learning!
Try some things and ask for help when something doesn't work. You'll find a lot of help here!
Pat.
