Software Serial Not Working

Projects Programming
1

hi all,

I am having trouble in using software serial library. I have compiled and run the program below.
When I run, I see the serial monitor. It only shows "Goodnight moon!".
Why "Hello, world?" not shown?
and when I input any character from the serial monitor, not read by the myserial.

here is my code :

#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // RX, TX
void setup()
{
  Serial.begin(9600);
  Serial.println("Goodnight moon!");
  mySerial.begin(9600);
  mySerial.println("Hello, world?");
}

void loop() // run over and over
{
  if (mySerial.available())
    Serial.write(mySerial.read());
  if (Serial.available())
    mySerial.write(Serial.read());
}

please, any body help me.

Because serial activity on pin 10 and 11 is not connected in any way with the serial monitor. You would have to connect a serial device to the software serial pins to see the "hello world".

what some examples of the serial device to be connected to the software serial pin so that I can see the "hello world"?

a serial terminal

I use a serial 16X2 LCD like this:

Hook that to pins 11, and power, and you have a second serial monitor.

The others seem to assume you want it to be displayed on the device connected. To me it sounds like you want to just show it on your computer (ie, for debugging).

You can do that with any serial terminal application and a USB TTL serial adapter.

Very cheap USB serial adapter:

or one of these, most which can also be used to program an Arduino Pro Mini or similar (the ones above can too, but you need to solder a wire onto a lead from the IC - the requirement for programming pro mini/etc is that the DTR pin is available):

or any of hundreds of other devices.

Thank you for your responses. I understand now.
