So you want to press a button that allows you to change between Fire2012() mode and SnowSparkle() mode?

First you will need to connect a button physically. Go through a tutorial on buttons and figure out how it works. Look up debouncing too.

Next, you will need a state variable to keep track of which mode your system is in. When you press the button it should change the state. In your loop you should then use an if else statement to decide which mode to call depending on the state. If you decide to add more patterns in the future you might want to look up switch cases.

You might get lucky and someone will just write the code for you however.

First, please read the posts at the top of the Forum which includes instructions on the proper way to post code here using code tags. Second, why do you make us read all of that code when no question is ever asked. The title is not the proper way to ask a question. Finally, why not tell us where the code came from, as there might be some clues there, too.
