How to Get Rotary Angle from a Grove Rotary Angle Sensor in Arduino

1) Connect the module to the A0 port.

2) Run the following code:

void setup() {
  Serial.begin(9600);
}

void loop() {
  int v = analogRead(A0);

  Serial.println(((v * 5 / 1023.0) * 300) / 5); // 5 = ADC reference voltage, 5 = shield voltage

  delay(1000);
}
