使用Arduino来实战! 首先要确定你的Arduino 的哪些引脚支持PWM输出,数字引脚上标记了 ~ 符号的就是支持PWM的。Arduino主控芯片为ATmega168或者ATmega328的3, 5, 6, 9, 10, 和 11引脚支持PWM,Arduino Mega的 2~13 , 44~46引脚支持PWM,老板子ATmega8的9,10,11脚支持PWM。 Arduino的库中通过analogWrite函数来完...
The Servo library supports up to 12 motors on most Arduino boards and 48 on the Arduino Mega. On boards other than the Mega, use of the library disables analogWrite() (PWM) functionality on pins 9 and 10, whether or not there is a Servo on those pins. On the Mega, up to 12 servo...
在调用Servo.attach(pin)方法之后,可能会有电机不转了,官网上关于servo库的介绍, The Servo library supports up to 12 motors on most Arduino boards and 48 on the Arduino Mega. On boards other than the Mega, use of the library disables analogWrite() (PWM) functionality on pins 9 and 10, wheth...

The PWM block generates square pulses of varying duty cycle depending on the input value sent to the block on the Arduino hardware pin.
The Arduino supports PWM on a subset of its output pins. It may not be immediately obvious which timer controls which output, but the following table will clarify the situation. It gives for each timer output the output pin on the Arduino (i.e. the silkscreened label on the board), the...
Timer1-Timer5 are available for Arduino Mega boards. Usage Before using any PWMTimerandchannel, you have to make sure theTimerandchannelhas not been used by any other purpose. AVR_PWM* PWM_Instance; PWM_Instance =newAVR_PWM(PWM_Pins, freq, dutyCycle); ...
