这是一个软件PWM控制Arduino D13引脚的例子。只需要一块Arduino即可测试此代码。 程序解析:由for循环可以看出,完成一个PWM周期,共循环255次。 假设bright=100时候,在第0~100次循环中,i等于1到99均小于bright,于是输出PWMPin高电平; 然后第100到255次循环里面,i等于100~255大于bright,于是输出PWMPin低电平。无论...
1) Arduino 2560 has 12 pins supporting PWM. They are from 2 to 13 included. 2) the PWM default frequency is 490 Hz for all pins, with the exception of pin 13 and 4,whose frequency is 980 Hz (I checked with an oscilloscope). 3) In order to change frequency on pin 'A', we have...
Use pulse-width modulation (PWM) to change the duty-cycle of square-wave pulses output by a PWM pin on the Arduino hardware. PWM enables a digital output to provide a range of different power levels, similar to that of an analog output. ...
