Exercise 1

const int R = 9;
const int G = 11;
const int B = 10;
const int PhotoR = A5;

int PhotoRValue = 0;

void setup()
{
  pinMode(R, OUTPUT);
  pinMode(G, OUTPUT);
  pinMode(B, OUTPUT);

  pinMode(PhotoR, INPUT);

  analogWrite(G, 255);


}

void loop()
{
  int brightness = 0;
  PhotoRValue = analogRead(A5);

  brightness = PhotoRValue;

  brightness = map(brightness, 0, 1023, 0, 255);
  analogWrite(G,brightness);

}
