Week 9 – Assignment

Concept:

For this assignment, I decided to create a gender reveal project. I used a red LED and a button to represent “girl,” and a blue LED and button to represent “boy.”

Implementation:

When the red button is pressed, the red LED (representing “girl”) lights up. Similarly, when the blue button is pressed, the blue LED (representing “boy”) turns on.

int yellowLED = 13; // yellow LED
int blueLED = 9;    //  blue LED
int yellowButton = A0; // yellow button 
int blueButton = A2;   // blue button 
void setup() {  
  pinMode(yellowLED, OUTPUT);    
  pinMode(blueLED, OUTPUT);        
  pinMode(yellowButton, INPUT_PULLUP); 
  pinMode(blueButton, INPUT_PULLUP);   
}

void loop() {
  int switchPositionYellow = digitalRead(yellowButton);  
  int switchPositionBlue = digitalRead(blueButton);     

  // Check if both buttons are pressed at the same time
  if (switchPositionYellow == LOW && switchPositionBlue == LOW) {
    digitalWrite(yellowLED, LOW);  
    digitalWrite(blueLED, LOW);     
    delay(500);               

    digitalWrite(yellowLED, HIGH);  
    delay(500);
    digitalWrite(yellowLED, LOW);

    digitalWrite(blueLED, HIGH);    
    delay(500);
    digitalWrite(blueLED, LOW);
  }
  
  // If only the yellow button is pressed
  else if (switchPositionYellow == LOW) { 
    digitalWrite(yellowLED, HIGH);   // Turn ON yellow LED
    digitalWrite(blueLED, LOW);      // Turn OFF blue LED
  }

  // If only the blue button is pressed
  else if (switchPositionBlue == LOW) { 
    digitalWrite(yellowLED, LOW);    // Turn OFF yellow LED
    digitalWrite(blueLED, HIGH);     // Turn ON blue LED
  }

  // If neither button is pressed
  else {
    digitalWrite(yellowLED, LOW);    // Turn OFF both
    digitalWrite(blueLED, LOW);
  }
}
