【Landzo C1试用体验】呼吸灯

先来看看Arduino UNO 引脚的功能

而呼吸灯的效果是利用PWM 数据转模拟的功能来实现的，
在选用引脚上一定要使用PWM引脚输出功能

代码如下：

1. int led = 11;           // the pin that the LED is attached to
   
2. int brightness = 0;    // how bright the LED is
   
3. int fadeAmount = 5;    // how many points to fade the LED by
   
4. 
   
5. // the setup routine runs once when you press reset:
   
6. void setup() {
   
7.   // declare pin 9 to be an output:
   
8.   pinMode(led, OUTPUT);
   
9. }
   
10. 
    
11. // the loop routine runs over and over again forever:
    
12. void loop() {
    
13.   // set the brightness of pin 9:
    
14.   analogWrite(led, brightness);
    
15. 
    
16.   // change the brightness for next time through the loop:
    
17.   brightness = brightness + fadeAmount;
    
18. 
    
19.   // reverse the direction of the fading at the ends of the fade:
    
20.   if (brightness == 0 || brightness == 255) {
    
21.     fadeAmount = -fadeAmount ;
    
22.   }
    
23.   // wait for 30 milliseconds to see the dimming effect
    
24.   delay(30);
    
25. }
