arduino ifndef

When programming to Arduino, because there is no debugging tools, often through the use of serial communication to call Serial.print and SERIAL.PRINTLN output Arduino running the relevant information, and then on the computer with the Arduino The IDE's serial monitor to see the print out information. Serial Monitor not only accepts data that
