Mega 328P-AU -> no Analog OUT on Pin 27 (A4)

Other Hardware 3rd Party Boards

Hello,

I finished a project with Mega 328P-AU.
I used brand new blank chip which I bootloaded with Nick Gammons tool.

I have used Arduino Nano for prototyping where Pin 27 (A4) working as OUTPUT.

On Pin 27 I have got only a LED (which doesnt work).

Any ideas why it doesnt work?

Regards,
Mav.

OK, here we go:

  • Post the code you are using (in "code" tags).
  • Post a diagram of your circuit indicating all parts including the LED and its resistor.
  • Put a picture - perfectly focused, showing all parts of your setup - on imgur and show it here as an image using "IMG" tags.
    Instructions.
