程式範例

 在此範例配合S4A IO Board 做簡單實驗,旋轉可變電阻時Arduino Serial Monitor輸出對應的數值

// to the pins used:

const int analogInPin = A1;

int sensorValue = 0;// value read from the pot

int outputValue = 0;// value output to the PWM (analog out)

void setup() {

  // initialize serial communications at 9600 bps:

  Serial.begin(9600);

}

void loop() {

  // read the analog in value:

  sensorValue = analogRead(analogInPin);

  // map it to the range of the analog out:

  outputValue = map(sensorValue, 0, 1023, 0, 255);

  // print the results to the serial monitor:

  Serial.print(“sensor = ” );

  Serial.print(sensorValue);

  Serial.print(“\t output = “);

  Serial.println(outputValue);

  delay(100);
