Pros

void loop() int sensorValue = analogRead(A0); Serial.println(sensorValue); delay(100);

Who it’s for

The board is a , meaning that every pin on the shield connects directly to the corresponding pin on the Arduino. The shield does not create new GPIO ports – it only gives you a more convenient way to access the existing pins. All Arduino code that references pin numbers works exactly the same way whether the shield is mounted or not.

Solution: On most V5.0 shields that include RS‑485, you need to set the small jumpers toward the outside of the PCB. Many shields ship with the jumpers in the incorrect position for RS‑485 communications.
