Need help with Snapdragon LED glow project with button input

Hello People,

I need help from you guys to accomplish the following task -

I have successfully completed LED glow project for snapdragon using youtube video.
However, the project now is to accomplish this using a button.

So a button press should trigger LED glow on and off. I need quite detailed instructions for the same, a step by step guide how to do it.

Willing to pay to help with this if needed.

Hope you guys can provide me with some pointers.

Thanks
