I have an unrelated problem with this project unfortunately. Everything appears to be wired up properly yet the button with the 1 Megaohm resistor going into it does not seem to be outputting anything to analogRead(). The other three work so I can assume the ladder wiring is correct and I know the button isn't faulty. The pull down is working as well.
In my Serial Monitor I just continue to get 0 when I press it. Is it possible the resistor is faulty? Any tips for troubleshooting this? Thanks.
EDIT:
Just tried a different valued resistor yet the output remained 0. I rewired the button and it still isn't doing anything. The pins are placed in the breadboard in the correct direction. I'm at a loss but I'll keep fooling around for now.
EDIT:
I rewired the entire circuit on a larger breadboard and it works. I have no clue what I had wrong before. Darn! XD
