Run Void *** when button is pressed

Arrch:
This seems to be one of those Give me the code for it to do what I want, I don't want to actually how to code type of posts.

In some ways it may appear like that. I've been working on this project for 8 weeks and have built a fine matrix with over 620 led's, had to learn to solder correctly, design circuit boards after learning the software to do that, had to learn about transistors, IC's, power management, resistors, diodes, you name it. I'm studying as fast as I can and have come a long way in those 8 weeks.

My back is against the way, I have to get this finished in the next day or two as it's a CHRISTMAS DISPLAY and a present for someone. There's no point in me finishing it in February.

I have managed to learn everything I can in these past weeks and this is the first time I've honestly needed some help.

I understand the reasons for "guiding" people and helping them to learn, and I will, but as for this project....... I NEED HELP TODAY
