I'm planning to start building some stuff with my arduino. I have had it for about 2 years, but I was frustrated with it for the first few weeks because I didn't understand how to program it and use it. So after about a month of trying, I put it on a shelve and forgot about it. Until yesterday I took it out again and began fiddling with it. From messing with it, I figured out how to program it to do basic actions. Here I will show what I figured out so that other beginners can start using their arduino's too. This is done on a iMac using and arduino UNO, so it might may be difficult to follow what I'm doing if you are using something else.
