41 | Beginning with Arduino2. Connect one end of photocell to 5V on the board. Connect the other end of thephotocell to the ‘middle’ leg of the potentiometer. Also connect a wire from the otherend of the photocell to A0 on the board.3. Connect one of the outer legs on the potentiometer to GND on the board.4. Connect part of the photocell and potentiometer, as indicated in the circuit below, ontothe breadboard, using M-F jumper leads.5. Connect breadboard to Intel® Galileo Gen 2 board using selection of M-M and M-Fjumper leads.6. Connect LED to pins 11 (long lead) and GND (short lead).7. Place paper diffuser onto LED.
A TEACHER’S GUIDE TO THE INTEL® GALILEO | 42Coding1. Open the Arduino IDE. Check that the COM port assigned to the Intel® board (go to‘Device Manager’ to check), matches the correct COM port according the the IDE.2. Check also that the correct Intel® board has been selected.3. Copy and paste the code below, noting value set for photocell. (You can calibrate to yourroom setting using the 10K potentiometer.)int ledPin = 11; // LED connected to digital pin 11const int analogInPin = 0; // Analog input pin that the potentiometer is attached toint sensorValue = 0; // value read from the potint outputValue = 0;void setup() {pinMode(ledPin, OUTPUT); //Serial.begin(9600);}void loop() {// read the analog in value:sensorValue = analogRead(analogInPin);Serial.print("sensor value in is ");Serial.println(sensorValue);// logic for night lightoutputValue = map(sensorValue, 0, 1023, 0, 255);if (outputValue < 102) {analogWrite(ledPin, outputValue);
