The image wasn't clear enough, so I hope this one is better to see the wiring diagram. I have already read in another topics of this forums and in the internet, but any of them worked for me.ĮDIT 1: I'm only simulating both of Arduinos on Proteus, I don't have the hardware with me right now. Serial.println("Testing from serial port2") Using the real hardware UART serial port provides much better performance and avoids SoftwareSerial's many issues. Teensy does have a hardware UART serial port available. The ATmega328 also supports I2C (TWI) and SPI communication. This is necessary on Arduino Uno, because there is no unused hardware UART serial port. On Arduino boards, the main hardware serial port is used for programming and sending messages to the Arduino Serial Monitor. Serial.begin(9600) // put your setup code here, to run once: A SoftwareSerial library allows for serial communication on any of the Unos digital pins. The pic of my simulation with the circuit is this:įor 1 Serial (the data receiver): #include įor 2 Serial (the data sender): String str

I know that I can do the otherwise, but I'm testing this, because in my future project I will need to use this software serial port to read input data, so this is just a test. The 2 Serial will send data to 1 Serial, and 1 Serial will receive this data through a Software Serial port, and then re-write the data received to Hardware Serial Port, but I can't read this, and when I try to print what is available is software serial port, always shows 0. This tutorial will walk you through the lines of code that set up and use this library. A complete example of using the SoftwareSerial library can be found in softwareserialdemo.ino. I'm trying to communicate 2 Arduinos Uno, the 1 Serial (name of the first Arduino Uno) and 2 Serial (name of the second Arduino Uno). The SoftwareSerial library can configure other digital pins on your Arduino so that they can be used for serial communication.

I can't read data using SoftwareSerial library, because SoftwareSerial.available() is always 0, no matter what I do.
