Lab 6 - Light Sensor

Purpose:
Make the light turn on and off using the light sensor

Equipment:
Light sensor (x1)
resistor (10k Ohm) (x1)
LED
resistor (330 Ohm) (x1)
wire (x6)


Program Details:
I used the one off newinnovators.ca

Time to Program and Complete:
5 minutes

Results:
N/A

Photo/Video Proof:




























Program: 
int lightPin = 0;
//sets a value for lightPin
int ledPin = 9;
//sets a value for ledPin

void setup()
//declares a setup
{
  pinMode(ledPin, OUTPUT);
//sets ledPin as an output
}

void loop()
//declares a setup
{
//start of loop
  int lightLevel = analogRead(lightPin);
//introduces a new variable; lightLevel
  lightLevel = map(lightLevel, 0, 900, 0, 255);
//lightLevel is equal to...
  lightLevel = constrain(lightLevel, 0, 255);
//sets a new value for lightLevel
  analogWrite(ledPin, lightLevel);
//turns on ledPin for a value of lightLevel

}
//end of loop

Program Modifications:
N/A
