最近对 arduino 很感兴趣，因为它的开源，编写简单，用它来控 制电调。通过调节电位器来控制无刷电机的转速。程序是根据 arduino 中自带的 Servo 库中示例程序 knob 改编而成！当然也是根据电调的 通信协议 PPM 来修改的！如图： 程序代码： #include Servo myservo; // create servo object to control a servo int potpin = A0; // analog pin used to connect the potentiometer int val; // variable to read the value from the analog pin void setup() { myservo.attach(9,1000,2000); // attaches the servo on pin 9 to 

the servo object delay(2500); myservo.writeMicroseconds(1000); delay(2000); } void loop() { val = analogRead(potpin); // reads the value of the potentiometer (value between 0 and 1023) val = map(val, 0, 1023, 0, 179); // scale it to use it with the servo (value between 0 and 180) myservo.write(val); // sets the servo position according to the scaled value delay(15); // waits for the servo to get there } 说明：A0 引脚接电位器来控制电机速度，9 引脚接电调的信号线， 电机启动后调节电位器由小逐渐调到最大，电机就开始由慢逐渐 变快旋转起来。
