Fade | |
This example shows how to fade an LED on pin 9 | |
using the analogWrite() function. | |
This example code is in the public domain. | |
*/ | |
int led = D0; // the pin that the LED is attached to | |
int brightness = 0; // how bright the LED is | |
int fadeAmount = 5; // how many points to fade the LED by | |
// the setup routine runs once when you press reset: | |
void setup() { | |
// declare pin 9 to be an output: | |
pinMode(led, OUTPUT); | |
} | |
// the loop routine runs over and over again forever: | |
void loop() { | |
// set the brightness of pin 9: | |
analogWrite(led, brightness); | |
// change the brightness for next time through the loop: | |
brightness = brightness + fadeAmount; | |
// reverse the direction of the fading at the ends of the fade: | |
if (brightness == 0 || brightness == 255) { | |
fadeAmount = -fadeAmount ; | |
} | |
// wait for 30 milliseconds to see the dimming effect | |
delay(30); | |
