combining codes

Hi All, I am new to all this but trying to learn, my question is can I combine codes to one another and if so is there a way in what order they can be done for example: I want to make a servo tester with an LCD, the use of push buttons and a knob, I have seen many examples on the net but none with I am looking for. There are very usable codes out there so what I am asking is can I take those codes and combine them for what I am looking for??
