Hi Mikey,

We will be glad to help you, but you need to give us more information as to where you are getting stuck. Have you taken a look at our interrupts video tutorial? That should get you started with pin change interrupts.

I would suggest first simplifying the problem by using the push button. This is a single button that will work much the same way your 12 button keypad works, but it will be easier to reason about in the code.
