Ok so I doubt this will be a hard problem to fix. I really need to set up multiple html buttons that each controls a separate pin. Like a button to control pin 4 and a different one for pin 5 and so on.
As you can see my code is below. I already have the pins enabled and everything is wired correctly I just need to make a separate button to control each pin.
