Serial communication Arduino

From my last post (Arduino-oled-display) I added a new function that allows me to send notification/messages from my terminal (linux) to my Arduino and it shows it through the little Oled screen. Here I will share the commands and code lines to get done the serial communication on your project. void loop() { while (Serial.available() > 0) { char recieved = Serial.read(); inData += recieved; // Process message when new line character is received if (recieved == '\n') { Serial.print("Arduino Received: "); Serial.print(inData); //digitalWrite(ledPin, HIGH); // if(inData == "HELLO\n") { // DON'T forget to add "\n" at the end of the string. Serial.println("HELLO"); //digitalWrite(ledPin, LOW); display.clearDisplay(); display.setCursor(0,0); display.setTextSize(2); display.print("Hi jose!"); display.display(); delay(3000); } inData = ""; // Clear received buffer } } }
