Saw 3DSage's tutorial from YT and got an idea Press a or b. AND: Both a and b need to be pressed to set the value to 1 OR: either a, b, or both need to be pressed to set the value to 1 NOT: The value is at 1 unless a is pressed. (pressing b does nothing) 1 Bit: This is the combination of 2 NOT gates. The value will stay locked and remember the value it was in. pressing a will set it to 1 and pressing b will set it to zero. IT will stay that way even you aren't pressing the key. This only applies as long as it's being powered (or in this case, the green flag is clicked and the project is running)
