Analog Output

LED Dimming

• File->Sketchbook->Examples->Analog->Fading

void loop() {

 for(value = 0 ; value <= 255; value+=5) // fade in (from min to max) 
 { 
   analogWrite(ledpin, value);           // sets the value (range from 0 to 255) 
   delay(30);                            // waits for 30 milli seconds to see the dimming effect 
 } 
 for(value = 255; value >=0; value-=5)   // fade out (from max to min) 
 { 
   analogWrite(ledpin, value); 
   delay(30); 
 }
