本期创客G坊教朋友们使用Arduino编写一段使用电位器控制舵机的小程序
两种方法,1、arduino有自带的控制舵机的库函数;2、舵机通过PWM控制,搞懂原理后,控制起来也不复杂。可参考网页链接
attach()
Description
Attach the Servo variable to a pin. Note that in Arduino 0016 and earlier, the Servo library supports only servos on only two pins: 9 and 10.
Syntax
servo.attach(pin)
servo.attach(pin, min, max)Parameters
servo: a variable of type Servo
pin: the number of the pin that the servo is attached to
min (optional): the pulse width, in microseconds, corresponding to the minimum (0-degree) angle on the servo (defaults to 544)
max (optional): the pulse width, in microseconds, corresponding to the maximum (180-degree) angle on the servo (defaults to 2400)
Example
#include <Servo.h>
Servo myservo;
void setup()
{
myservo.attach(9);
}
void loop() {}See also
