Week 1 Lab 1 from Lina Giraldo on Vimeo.

Code:

// declare variables:

int switchPin = 2;      //  digital input pin for a switch

int yellowLedPin = 3;   //  digital output pin for an LED

int redLedPin = 4;      //  digital output pin for an LED

int switchState = 0;    // the state of the switch

 

void setup() {

  pinMode(switchPin, INPUT);       // set the switch pin to be an input

  pinMode(yellowLedPin, OUTPUT);   // set the yellow LED pin to be an output

  pinMode(redLedPin, OUTPUT);      // set the red LED pin to be an output

}

 

void loop() {

  // read the switch input:

  switchState = digitalRead(switchPin);

 

  if (switchState == 1) {

    // if the switch is closed:

    digitalWrite(yellowLedPin, HIGH);    // turn on the yellow LED

    digitalWrite(redLedPin, LOW);       // turn off the red LED

  } 

  else {

    // if the switch is open:

    digitalWrite(yellowLedPin, LOW);   // turn off the yellow LED

    digitalWrite(redLedPin, HIGH);     // turn on the red LED

  }
