Unit 3: Multi Light LEDs

 

 

Code for Sketch One: 

 
const int PIN_RED = 11;    // Red LED pin
const int PIN_GREEN = 10;  // Green LED pin
const int PIN_BLUE = 9;    // Blue LED pin
 
// Function to set the color of the LED
void setColor(int R, int G, int B) {
  analogWrite(PIN_RED, R);
  analogWrite(PIN_GREEN, G);
  analogWrite(PIN_BLUE, B);
}
 
void setup() {
  // Set all three pins to output mode
  pinMode(PIN_RED, OUTPUT);
  pinMode(PIN_GREEN, OUTPUT);
  pinMode(PIN_BLUE, OUTPUT);
}
 
void loop() {
  // Continuous Green state
  setColor(0, 255, 0);   // Green
  delay(10000);           // Stay green for 10 seconds
 
  // Flashing Green (Paused) state
  for (int i = 0; i < 5; i++) {
    setColor(0, 255, 0); // Green
    delay(500);           // On for 0.5 seconds
    setColor(0, 0, 0);   // Off
    delay(500);           // Off for 0.5 seconds
  }
 
  // Flashing Red (Triggered) state
  for (int i = 0; i < 5; i++) {
    setColor(255, 0, 0); // Red
    delay(500);           // On for 0.5 seconds
    setColor(0, 0, 0);   // Off
    delay(500);           // Off for 0.5 seconds
  }
 
  // Continuous Red (Off) state
  setColor(255, 0, 0);   // Red
  delay(10000);           // Stay red for 10 seconds
}
