Simple light sensor connected to a Luminet2 board with conductive thread.
|
- + connected to power (VCC)
- - connected to ground (GND)
- S connected to an input pin (A0)
The code uploaded to Luminet2 lights the LED green when it becomes darker.
The code is written in the Arduino IDE and is uploaded to the Luminet2 board through a serial connection.
{CODE(colors="c")}
int greenLed=9; //the pin number for the Green LED
void setup() {
//inform the micro-controller that a sensor is connected to pin A0
pinMode(A0, INPUT);
//inform the micro-controller that an actuator (in our case the green LED) is connected to pin 9
pinMode(greenLed, OUTPUT);
}
void loop() {
if(analogRead(0)<100){
digitalWrite(greenLed, HIGH);//turns the green LED ON
}else{
digitalWrite(greenLed, LOW); //turns the green LED OFF
}
}{CODE}
