Arduino Code

Aurora: Here's the code I was using at the workshop w/ a ceramic light resist. As the light levels lowered, the LED would blink rapidly, creating a fade effect. However! When I tried it again in my room, I got crappy results. This might also be because I was storing the light resistor in a bag of metal objects, and it may have been scratched/etc.

// Light Sensor Analog Changes Light Value


int val;
int inPin = 4;
int ledPin = 3;

void setup()
{
Serial.begin(9600);
pinMode(ledPin, OUTPUT);
}

void loop()
{
val = analogRead(inPin);
Serial.println(val);
delay(500);
digitalWrite(ledPin, HIGH);
delayMicroseconds(val);
digitalWrite(ledPin, LOW);
delayMicroseconds(1024-val);

}
