Wiring Sensor and Actuator

Use the bus cable in the Grove Starter Kit to connect the relay, LED, and light sensor to the Base Shield as follow:
- Relay ---> D2
- LED ---> D3
- Light Sensor ---> A0

Hardware Connection

Relay Control based on Light Sensor with Intel Edison

Control Relay base on Light Sensor 
*/

// These constants won't change.  They're used to give names
// to the pins used:
const int analogInPin = A0;  // Analog input pin that the potentiometer is attached to
const int analogOutPin = 3; // Analog output pin that the LED is attached to
const int relayPin = 2;     // Digital Putput pin that Relay is attached to

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);
  // initialize digital pin 2 as an output.
   pinMode(2, OUTPUT);
}

void loop() {

  // read the analog in value:
  sensorValue = analogRead(analogInPin);
  // map it to the range of the analog out:
  outputValue = map(sensorValue, 0, 360, 0, 255);
  // change the analog out value:
  analogWrite(analogOutPin, outputValue);

  // print the results to the serial monitor:
  Serial.print("sensor = " );
  Serial.print(sensorValue);
  Serial.print("\t output = ");
  Serial.println(outputValue);


  if (sensorValue<100){
    digitalWrite(relayPin, HIGH);

  }
  else if (sensorValue>200)
  {
    digitalWrite(relayPin, false);
      Serial.print("\t Relay Off!");
  }

  // wait 100 milliseconds before the next loop

      delay(100);
