Hello.
I was reading about how to power LED's to microcontroller and I saw Sink and Source mode, I undestood the source mode very well. But the sink mode didn't made much sense to me.
How if a pin is low, the led will be on, doesn't the pin when its low is like an unconnected pin, or does it connects to ground?
Thanks
