Quick question:
If I have multiple momentary switches/buttons on four different inputs, how would I go about responding to only one button, even if others are pressed while the first is being pressed, i.e., button1 turns on LED1, button2 turns on LED2, etc., but LED2 can't be on while LED1 is on.
I'm looking for a direction to get me started here, rather than just the answer; learning is a process.
