使用Blynk将ESP8266连接到Arduino Uno

Question

我正在做一个项目，在这个项目中，我试图通过ESP8266和Arduino uno使用Blynk应用程序打开无线上网LED。我相信电路是正确设置的，因为我能够运行一个空脚本，并通过串行监视器发送"AT“命令并获得反馈。ESP8266也出现在我的wifi设置上。然而，从那以后，我试图在blynk应用程序上安装一个快速启动设备，这就是我被困在那里的地方。

主要的错误似乎是，我无法下载必要的库"ESP8266_Lib.h"，以便该程序，Blynk最初提供给您运行。我试图在github上下载最新版本的blynk库，但这仍然没有帮助。

经过这个阶段的项目，我希望搬到一个阿德拉果引理板，并希望这将不会引起任何进一步的问题。提供的代码Blynk和错误消息如下：

BlynkESP8266_Lib仅在发布页面上的Blynk库的发行版zip中可用。见资产部分。

将BlynkESP8266_Lib文件夹从zip复制到草图文件夹中的libraries文件夹中。(草图簿文件夹的位置设置在Arduino IDE的Preferences对话框中。)
