I want to add five buttons on this code but i have trouble coding it and connecting the electrical components together, can someone please give me a hand?



// Use if you want to force the software SPI subsystem to be used for some reason (generally, you don't)

What do you want these buttons to actually do?

If you stick with that style of coding then any button can only be looked at every 0.1 * 100 = 10 seconds, because this is blocking code.
