METRO MINI 328 Questions

[BURevisfan]

Good morning All,

I'm having a rough morning and blanking on concepts I should know :)

I have a couple questions I'd like confirmed on the Metro Mini 328.

1) The Analog Pins A0-A5 can be used as Digital Outputs.... right?

2) Assuming yes to Question #1, for digital use they would be defined and used as Pins 14-19?

3) Does anything need to be down to AREF when using them as digital outputs?

thanks in advance!

Yes

Yes

but can also just use the Ax names, ex:

Code: Select all

pinMode(A0, OUTPUT);
digitalWrite(A0, HIGH);

3) Does anything need to be down to AREF when using them as digital outputs?

No
