I am building a scale RC helicopter and ordered a bunch of 3mm LEDs to give it some nice navigation and strobe lights which I plan to drive with an Arduino Nano.
Problem is that I goofed and didn't notice that the LEDs are 12v until they arrived. I know that the Arduino Nano can accept 12V on pin 30, but I think the voltage output on any of the "D" or "A" pins is always 5v (correct??).
If the voltage output of the Arduino pins is 5v, then how can I drive the 12v LEDs using the Arduino, or is it impossible?
