Arduino：如果/ Else问题

情况：我的网页上有两个按钮 . 一个发送到PubNub通道的JSON字符串{“lightRight”：“1”}和一个发送{“lightRight”：“0”}，无论我在Arduino Sketch中做什么我都无法进入“on”空隙光功能的一部分 .

我从arduino的串行输出中知道我正在从网页接收通信 . 如果我将布尔值翻转为关闭然后我能够获得“LED高”输出，但是我不再能够获得“LED低” .

我想要修改的代码可以在这里找到 .

我很可能已经从示例中删除了很多代码，这就是为什么我要包含它，但运行股票代码我似乎无法让它工作 .

我不是开发人员，所以如果我不把事情称为正确的条款，我感到非常抱歉 . 我将从纠正中学习 .
