Hi again,
I solved the button issue and now i need help with a different issue.
Problem that i'm having is that I need more digital pins, I need 21 pins for my project and as far as I know arduino can only give me 19 pins.
I have googled for a solution and I found something called shift Register.
I'm think of connecting all my led strip to shift Register but on all examples led diode is used and they are connect to 5V on the arduino and on my project led strips uses mosfets and are connected to a 12v ac-adapter.
Here is my questions
Will a shift Register work for me and if not do you know a better solution?
Will connecting my led strips be the same as the exemples (image below) if not Do you know how i connect my led stips to a shift Register?
