I know how to switch a current sink with a higher source voltage (i.e., 12V source switched with 5V GPIO pin) using an NPN transistor. I also know how to switch a current source with the same source voltage using a PNP transistor (5V source switched with 5V GPIO pin). But what is the best-practice w…
