Hi, I'm an Arduino novice and I want to make a super simple keyboard where I use two buttons to scroll up and down characters. For example, if I pressed the button, an A would pop up on the serial port, if I press it again, a B would show, etc. How do I make such a keyboard? Can anyone give me example code on how to do it? Thanks!
I know as a noob I should be solving my own problems but I just have no idea on how to make this, sorry
