Could someone give me a code piece how to initialize and use AO/A1 (analog pins) as Rx/Tx Serial I/O.
In which arduino board?
Ah, sorry, forgot. Arduino Nano
You can't select any pins for hardware Serial interface other than predefined 0 & 1. But you can create additional software-based serial port.
Read the documentation for SoftwareSerial library
#include <SoftwareSerial.h>
SoftwareSerial mySerial(A0, A1); // RX, TX
void setup()
{
// set the data rate for the SoftwareSerial port
mySerial.begin(38400);
mySerial.println("Hello, world?");
}
void loop() {}
Thanks. That's what I wanted to know, mySerial(A0, A1); // RX, TX
so mark the thread as "solved"
