Arduino Night Light
Intro: Arduino Night Light
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);
}
}

Why did you use the 10K resistors?Can you use the different values of resistors for this circuit?Please answer me. Thanks.
