Any Help please, Much appreciated.

So, you have a problem with some code you didn't post, that is supposed to interact with hardware that you didn't post links to.

i was able to compile one of them and got the fingerprint scanner to work but then nothing else works .

"It doesn't work" is the lamest complaint posted here. The code does something. You need to tell us what it actually does. You expect the code, realistically or not, to do something. You need to tell us what you expect it to do.

You have the external hardware connected in some mysterious way to the Arduino. You need to clear up that mystery.

Then, we can possibly help you.

This is my first post i didnt finish writing it, i was just trying to add everything for you to understand.
