Re: LEDs on Operator Console?
Oh I see. So I can take my LEDs that want 20mA and give them a resistor so they'll only draw 5mA and it will work fine on any pin, right?

And since the sink current is higher than the source current, the cathode goes to 3.3V and the anode should go to the pin, and they turn on by turning the pin off. Is that correct?
