      Hey everyone. I am currently looking to add a simple red power led as well as a power button to my raspberry pi 3. The LED is straight forward, I just want it to glow red when on, nothing when off. My question here is what should I be looking at as far as resistors go? I saw a guide that suggested plugging an led in with no resistor as long as it was a 12v led. Will this be ok or will it fry the gpio?

      As far as the power button goes, I'm looking to have the switch turn the pi and fan completely off and on when pressed. I have looked into a few of these add-ons however I can't move my power cable as I have a 3d printed case. I need someway to use the existing slot.

      Thanks for any help.
