Arduino Night Light
This project creates an automated night light. The lights will turn on automatically when the
room is dark, and off when the room is light.

Components Needed:

1x Arduino
1x Breadboard
3x 220 Ohm Resistors
1x 10K Ohm Resistor
3x LED's
Wires

Components can be found at http://egrobotics.com/store/
This Project uses and Arduino Board and LDR Add-on Kit

www.EGRobotics.com

Code:

void setup() {
  Serial.begin(9600);
  pinMode(3, OUTPUT); 
}
void loop() {
  int sensorValue = analogRead(A0);
  if (sensorValue < 200) { // To change the point at which the light turns on change this value.
    digitalWrite(3, HIGH);
  }
  else {
    digitalWrite(3,LOW);
}
}

<p>Why did you use the 10K resistors?Can you use the different values of resistors for this circuit?Please answer me. Thanks.</p>
Not work for me. Please help me!
<p>Wow this is cool :D thanks !</p>
