// ACTIVITY 3: LED with potentiometer
// Angeline Salas
// Irish Poblete

// Firstly, let's define the pin numbers
int potPin = A0;    // Potentiometer connected to analog pin A0
int ledPin = 13;    // LED connected to digital pin 13

int potValue = 0;   // Variable to store the potentiometer value

void setup() {
  // Then, set the LED pin as an output
  pinMode(ledPin, OUTPUT);  
}

void loop() {
  // Read the analog value from the potentiometer
  potValue = analogRead(potPin);  
  
  // We'll map the potentiometer value to a delay time range
  int delayTime = map(potValue, 0, 1023, 50, 200); // Potentiometer values range from 0 to 1023, delay time ranges from 50 to 200 milliseconds
  
  // Turn off the LED
  digitalWrite(ledPin, LOW);   
  // Wait for the calculated delay time
  delay(delayTime);             
  // Turn on the LED
  digitalWrite(ledPin, HIGH);    
  // Lastly, we wait for the same delay time
  delay(delayTime);
