Try this


void setup()
{
    Serial.begin(115200);
}

void loop()
{
    Serial.println(analogRead(1));
    delay(1000);
}

There's a different "pins_arduino.h" file for different boards, here's a listing.

When I connected the battery to Arduino ground the servo moved (once) but I couldn't contol it with the pot. After I changed "A" to "A1" I could control the servo with the pot.

I thought you changed "(1)" to "(A1)"? Anyway, is it working?

Thanks, Bob, but things seem to be working fine now, so I don't want to mess with things :melting_face:
