Will the pro micro power 12v LEDs if its through my pc usb? If not, would i just wire a 12v power supply to LEDs? Ive only built button boxes, however I want to use LED lighted buttons but not sure how I should go about doing it. Noob question I know. But i’m just getting into this sorta thing. Thanks.
The pro micro can not handle 12V (3.3v or 5V). A USB connection provide 5V. Connecting 12V to a led and then trying to connect that direcly and control that with an IO pin from the pro-micro will damage the board. You have to switch that indirectly, look at https://learn.sparkfun.com/tutorials/tr … i-switches
