Hallo gentlemen, good afternoon!
I’m coding a firmware using Arduino IDE, to upload it directly by USBasp on an ATmega328P-AU 3.3V based board.
I need to feed these 3.3V also to a component on the same project, using a pin as “on/off switch”.
The current I need from this pin is about 1mA, very low.
I know I can use, for this purposes, any of the “blue highlighted” pins in the attached picture.
The question is:
Can I have 3.3V also from analog pin ADC7, using the following code?
If yes, is that a voltage of the same type of voltage coming from “blue highlighted” pins?
Thank you very much indeed.
