微信小程序屏幕亮度、陀螺仪、系统方向、通话、扫码、震动的实例

由于这些实例需要使用手机的硬件，所以无法用电脑录屏演示。

wxml

<button bindtap="screenBrightness">屏幕亮度</button>
<button bindtap="setScreenBrightness">设置屏幕亮度</button>
<button bindtap="gyroscope">陀螺仪</button>
<button bindtap="deviceMotion">系统方向</button>
<button bindtap="makePhone">打电话</button>
<button bindtap="scanCode">扫码</button>
<button bindtap="vibrate">震动</button>

下面是js中绑定事件
