CIRCUIT

CODE


/*

 * Party Underwear

* by Andre Doria

*

* Turns on and off a light emitting diode(LED) connected to digital

* pin 13. The light is only turned on when the sensed ambient light

* is below a given number, obtained by analogRead() in pin 2 using

* a LDR

*/

int sensPin = 2;    // input pin for the LDR

int ledPin = 13;   // output pin for LEDs

int ambientLight = 0;       // variable to store the value coming from the sensor

void setup() {

pinMode(ledPin, OUTPUT);  // declare the ledPin as an OUTPUT

}

void loop() {

delay(100);

ambientLight = analogRead(sensPin);    // read the value from the LDR sensor

if(ambientLight<380){                 // If its dark

digitalWrite(ledPin, HIGH);  // turn the ledPin on

}else{                           // If its bright

digitalWrite(ledPin, LOW);   // turn the ledPin off

 }
}
