Difficulty Level: 4

Time to complete: 7 minutes

Challenge description: One led turns on when the sensor is covered and another turns on when it is not

Hint:

Answer:
int lightPin = 0;
int ledPin = 9;
int ledPin1 = 10;

void setup()
{
  pinMode(ledPin, OUTPUT);
  pinMode(ledPin1, OUTPUT);
  pinMode(lightPin, INPUT);
}

void loop()
{
  int lightLevel = analogRead(lightPin);
  lightLevel = map(lightLevel, 0, 900, 0, 255);
  lightLevel = constrain(lightLevel, 0, 255);
  
  if (lightLevel < 900);
  {
    digitalWrite (ledPin, HIGH);
    digitalWrite (ledPin1, LOW);
  }
  else if (lightLevel > 900);
  {
    digitalWrite (ledPin1, HIGH);
    digitalWrite (ledPin, LOW);
  }
}
