Arduino自帶的Servo函數庫只可以同時控制兩個模擬舵機。而且最好接到數字9 、 10腳上。想控制多個舵機就要使用到Arduino的Pwm功能了。 你也可以使用 32路伺服電機控制器 方便驅動多個舵機。

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() {}
