Arduino Beginner Series: Project 15: Using a slidy switch

Hello everyone!! Welcome to this post on Arduino LED Projects!!
Need a short introduction to what the Arduino is then click on LINK
Check out the breadboard intro right HERE

So here I’ve just used a SPDT (like a slidy switch) switch to switch between turning a yellow or blue LED on.

Demo:

So here’s what this super simple project looks like:

Things Required:

1. Arduino UNO
2. Breadboard
3. Jumper Wires
4. SPDT Switch
5. LEDs (x2)
6. 100 ohm resistors (x2)
7. Arduino IDE on computer

Functions used:

1. digitalWrite()
2. digitalRead()
3. pinMode()

Reference Material:

Here (LINK) you can learn both about SPDT switches and the project.

Code:

View on/ Download from Github: (LINK)

int spdt=3;
int blueled=12;
int yellowled=11;
int switch_val;

void setup() {
  // put your setup code here, to run once:
  pinMode(spdt, INPUT);
  pinMode(blueled, OUTPUT);
  pinMode(yellowled, OUTPUT);

}

void loop() {
  // put your main code here, to run repeatedly:
  switch_val= digitalRead(spdt);

  if(switch_val==1){
    digitalWrite(blueled, LOW);
    digitalWrite(yellowled, HIGH);
  } else {
    digitalWrite(blueled, HIGH);
    digitalWrite(yellowled, LOW);
  }

}
