Trabajo 06/ 2 Ejemplos con Analog Arduino

 Dos ejemplos más del ejercicio con Arduino y salidas Análogas.

1- Fading

Cuyo código es:

int ledPin = 9;    // LED connected to digital pin 9

void setup() {

  // nothing happens in setup

}

void loop() {

  // fade in from min to max in increments of 5 points:

  for (int fadeValue = 0 ; fadeValue <= 255; fadeValue += 5) {

    // sets the value (range from 0 to 255):

    analogWrite(ledPin, fadeValue);

    // wait for 30 milliseconds to see the dimming effect

    delay(30);

  }

  // fade out from max to min in increments of 5 points:

  for (int fadeValue = 255 ; fadeValue >= 0; fadeValue -= 5) {

    // sets the value (range from 0 to 255):

    analogWrite(ledPin, fadeValue);

    // wait for 30 milliseconds to see the dimming effect

    delay(30);

  }

}

2- Calibration

Cuyo código es:

// These constants won't change:

const int sensorPin = A0;    // pin that the sensor is attached to

const int ledPin = 9;        // pin that the LED is attached to

// variables:

int sensorValue = 0;         // the sensor value

int sensorMin = 1023;        // minimum sensor value

int sensorMax = 0;           // maximum sensor value

void setup() {

  // turn on LED to signal the start of the calibration period:

  pinMode(13, OUTPUT);

  digitalWrite(13, HIGH);

  // calibrate during the first five seconds

  while (millis() < 5000) {

    sensorValue = analogRead(sensorPin);

    // record the maximum sensor value

    if (sensorValue > sensorMax) {

      sensorMax = sensorValue;

    }

    // record the minimum sensor value

    if (sensorValue < sensorMin) {

      sensorMin = sensorValue;

    }

  }

  // signal the end of the calibration period

  digitalWrite(13, LOW);

}

void loop() {

  // read the sensor:

  sensorValue = analogRead(sensorPin);

  // in case the sensor value is outside the range seen during calibration

  sensorValue = constrain(sensorValue, sensorMin, sensorMax);

  // apply the calibration to the sensor reading

  sensorValue = map(sensorValue, sensorMin, sensorMax, 0, 255);

  // fade the LED using the calibrated value:

  analogWrite(ledPin, sensorValue);

}
