Pulse-width modulation (PWM) can be implemented on the Arduino in several ways. This article explains simple PWM techniques, as well as how to use the PWM registers directly for more control over the duty cycle and frequency. This article focuses on the Arduino Diecimila and Duemilanove models,...
I can’t explain the full details of PWM and how it works in this article because it would be long, but I did write a separatearticle explaining how pwm worksif you’re curious. The following Arduino PWM code sample reduces the voltage and average current output of pin 11: ...
To sample the generated signal connect default pins 22(PWM) and 32(Sampling) together. If you do not wish to generate PWM simply comment out the definition of constant GENERATE_PWM 如果不希望生成PWM,只需注释掉常量GENERATE_PWM的定义 Try to change the PWM_DUTY_PERCENT and see how to averaged...

// When setting up the NeoPixel library, we tell it how many pixels, // and which pin to use to send signals. Note that for older NeoPixel // strips you might need to change the third parameter -- see the // strandtest example for more information on possible values. ...

So a PWM frequency of 1kHz will be good enough for this application. The last PWM parameter, the Resolution is a measure for how many discrete levels of duty cycle that we can control. Look at the GIF image above, you’ll notice that the PWM duty cycle is increasing by 10% at each ...
