Hi guys, I need to communicate two Arduinos using TX/RX, but I don't have idea how to code this.. 'cause I'm newbie in Arduino programming.. Anyone can help & share to me for the codes in this case?

Any help would be greatly appreciated, thank you.

Then you are a long way from communicating between 2 Arduinos

Start with

void setup()
{
  Serial.begin(9600);
  Serial.println("Hello World");
}

void loop()
{
}

Upload it and open the Serial monitor

What is it that you want to communicate between the 2 Arduinos ?

You need to study some of the examples that come with the Arduino IDE and read some tutorials to learn the basics of Arduino programming.

For the communication with another Arduino you can use SoftwareSerial to create an extra serial port on your Uno.
