Going to be straightforward from the start, I have no experience with Arduino but my project requires low costs and Arduino functions fit my needs.
I’m using the Arduino (looking to be the Metro Mini) to control an Led Strip to Light up slowly beginning at a set time. A Potentiometer is used to set the wait time until the strip is activated. The problem is that the Strip is 12 Volts and the Metro Mini has a USB port that is 5 Volts. I have a DC Jack socket for a circuit board that I can use, however, is it smart to power the Metro Mini with 12V too if it is only controlling the brightness and when the LEDs turn on?
