Inside the loop function, we have an if statement that is checking to see if there is data waiting in the serial buffer; “Serial.available“. In simple terms, we’re checking to see if we have sent a command to it. If there is data, we enter the if statement. ...

If you have selected the wrong board, change it to the correct one and upload to the board again. You can display text using the Serial.print() function. Strings (text within double quotes) will be printed as is (but without the quotes). For example, the following code: Serial.print(...
