1、SG90 MG90S 9g舵机
舵机是一种位置（角度）伺服的驱动器，适用于那些需要角度不断变化并可以保持的控制系统,比如人形机器人的手臂和腿,车模和航模的方向控制。舵机的控制信号实际上是一个脉冲宽度调制信号( PWM信号),该信号可由FP-GA器件、模拟电路或单片机产生。
信号线（黄线）红线（电源线）棕色(地线）
舵机的控制一般需要一个20ms左右的时基脉冲（周期），该脉冲的高电平部分一般为0.5ms-2.5ms范围内的角度控制脉冲部分，总间隔为2ms（高电平时长）。连接上示波器情况如图
改变高电平时长可以控制舵机转到相应角度，以180度角度伺服为例，那么对应的控制关系是这样的：
高电平时长 | 舵机角度位置 |
0.5ms | 0度 |
1.0ms | 45度 |
1.5ms | 90度 |
2.5ms | 180度 |
2、舵机角度控制
案例说明：
- 阿里云端输入角度，控制舵机旋转至对应位置。
- 注意：本案例使用GPIO3控制舵机，且只支持Haas2.0版本系统。
- 需要准备Haas506开发板，SIM卡，9g舵机，各种连接线。
（1）引脚配置
- Haas2.0有两个WPM引脚GPIO3,GPIO39（1.0版本程序没有相关功能），两个引脚适用频率范围不同
GPIO3 | GPIO39 |
0~99hz | 100~10khz |
- 案例使用GPIO3 。 在board.josn配置设备节点，即GPIO3为"pwm_lpg"。

}（2）PWM脉宽调制
- 舵机的控制需要一个20ms左右的时基脉冲（周期），脉冲频率为50Hz。
该脉冲的高电平部分范围一般为0.5ms-2.5ms。占空比2.5~12.5%。
设置好需要的频率与占空比就可以了控制舵机转动。 - 2.2版本获取IMEI号接口有更新，需要更改以下内容（Ctrl+F 查找modem）

（1）添加物模型
（1）在阿里云物联网平台创建产品
填写产品名称、选择自定义品类，选择直连设备，选择联网方式-蜂窝，数据格式-ICA，点击确认。
创建完成后，打开动态注册
（2）编辑自定义功能
点击所建立的产品：选择查看、点击功能定义和选择编辑草稿
添加自定义功能：属性、功能名称、标识符、数据类型、布尔值、读写类型
(数据使用的是0~180°，代码中对数据进行了相应的转化)
发布上线
（3）添加设备
在产品下，添加一个设备：选择产品名、填写DeviceName(自定义，最好将设备的IMEI作为该名称)
（4）获取ProductSecret，ProductKey填入程序位置（第254行）
（2）烧录程序
打开串口工具，查看程序运行是否成功
