在Netduino中连接3.3v gnd端口5数字伺服

我的伺服系统是：14sec.html

不工作！为什么？有人已经做了一些有用的事了？

}

我称之为：

   Servo tt = new Servo(Cpu.PWMChannel.PWM_5);
            tt.Degree = 30;
            tt.setRange(1000, 2000);
            tt.Dispose();
        }

Answer 2

我没有使用那个库，但伺服不应该由3.3v供电，你应该把它单独连接到5v引脚。

您可以尝试的另一件事是创建一个新的PWM：

PWM servo = new PWM(Pins.GPIO_PIN_D9);

还有，所以我们可以帮忙，你应该描述它的行为.如果它抽搐，慢慢移动，什么的.再加上你连接它的方式(图表，照片)。
