WEEK 4 - 2 Switches 2 LED's

This week we moved onto 2 switches to control 2 LEDs.

Here is an image of my completed circuit:

Here are 2 video's of the switches, notice they have different functions simply by making simple alterations to the code:

And finally here is the code used for the circuit:

int ledPin = 13; // choose the pin for the LED

int inPin = 2; //choose the input pin (for a pushbutton)

int ledPin2 = 10;

int inPin2 = 3;

int val = 0; //variable for reading the pin status

int val2 = 0; 

void setup() {

  pinMode (ledPin, OUTPUT); //declare LED as output

  pinMode (inPin, INPUT); //declare pushbutton as input

  pinMode (ledPin2, OUTPUT); //declare LED as output

  pinMode (inPin2, INPUT); //declare pushbutton as input

}

void loop() {

  val = digitalRead(inPin); //read input value

  if (val == HIGH) { //check if the input is HIGH (button Released)

  digitalWrite (ledPin, LOW); //turn LED OFF

  } else 

   digitalWrite (ledPin, HIGH); //turn LED ON

  val2 = digitalRead(inPin2); //read input value

  if (val2 == HIGH) { //check if the input is HIGH (button Released)

  digitalWrite (ledPin2, LOW); //turn LED OFF

  } else 

   digitalWrite (ledPin2, HIGH); //turn LED ON

 }
