In your household or @work:
int ledPin = 1; // LED connected to digital pin 9
void setup() {
// nothing happens in setup
}
void loop() {
// fade in from min to max in increments of 5 points:
for(int fadeValue = 0 ; fadeValue <= 255; fadeValue +=5) {
analogWrite(ledPin, fadeValue); // sets value (range from 0 to 255):
delay(30); // wait for 30 milliseconds to see the dimming effect
}
// fade out from max to min in increments of 5 points:
for(int fadeValue = 255 ; fadeValue >= 0; fadeValue -=5) {
// sets the value (range from 0 to 255):
analogWrite(ledPin, fadeValue);
// wait for 30 milliseconds to see the dimming effect
delay(30);
}
}
int led = 11; // LED connected to digital pin 9
int LDR = A0; //analog pin 0
void setup() {
Serial.begin(9600);
pinMode( led, OUTPUT );
}
void loop() {
int LDRReading = analogRead(LDR);
Serial.println(LDRReading);
LDRReading = map(LDRReading, 600, 50, 0, 255);
