The program now does what i want it to, but because its in a loop it keeps printing out to the serial over and over.
Its pretty much there, just needs some optimization.

Paul i hope you can see what ive done with "assigning a ticket" so to speak. I probably didnt explain what i meant that well.

I'm now working on how i can write it so that the button code is universal for all buttons but just subs in the values that are relevant. Otherwise once ive loaded the full 6 buttons it'll look pretty clumsy! plus ill learn more in the process.

//Define pins here
//Define 6 pins 
 int F1button = 2;
 int F2button = 3;
 int F3button = 4;

?? six?
Comments, [Thanks to @ PaulS] are a pointer to your thinking,
@PaulS (Thank you for the lesson)...
Always change the comments to reflect your thoughts about the line of code you are currently writing...
Comments are cheap... Never appear in the compiled code.
Otherwise you are creating a map to nowhere...

Doc

just 3 for now but will be 6.

i like paul's code, looks real neat, will definitely save me copy and pasting the button handling and the printing 6 times over. Now to understand it.... :cold_sweat:
