Re: light up buttons
we already soldered resistors on the leds, so we dont actually need them? The voltage i thought is 5V at 10mA, to which can run the LED for a short period of time, but since 5V leds have a 5V peak, they run off extremely low amperage when at 5V. So we are putting a resistor on to make the LED run at 10mA at 3.5-4V.

What you are saying is we dont need to do that, as in just hook the pin to the led to the gound with no resistor?
