Hi, I'm currently working on a project which involves at least 16 buttons and 16 LEDs. For the sake of example, I'll say it's 2 rows of 8 buttons and 2 rows of 8 LEDs. Because of the fact that the Arduino simply doesn't have that many IO pins, I'm planning on using shift registers for the buttons …
