Dose anyone know how to use analog pin 6/7 as digital outputs tried the following and it has no effect (i am using a Nano)
pinMode(20, OUTPUT);
digitalWrite(20, LOW);
What does the processor data sheet say?
i have the output on the Arduino Nano.
That isn't the processor data sheet.
The additional anlogue inputs are simply connected to the analogue input mux, they don't have digital input capability.
can i use them as digital outputs?
No
ok thanks for your help
