使用 Blynk 将 ESP8266 连接到 Arduino Uno

Connecting an ESP8266 to an Arduino Uno using Blynk

我正在做一个项目,我试图通过 ESP8266 和 Arduino uno 使用 Blynk 应用程序通过 wifi 打开 LED。我相信电路设置正确,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 设置中。然而,从那里我试图在 blynk 应用程序上设置一个快速启动设备,这就是我被卡住的地方。

主要错误似乎是我无法下载必要的库,“ESP8266_Lib.h”,为了程序,Blynk 最初给你,运行。我试图在 github 上下载最新版本的 blynk 库,但仍然没有帮助。

在项目的这个阶段之后,我希望转移到 adrafruit gemma 板,并希望不会引起任何进一步的问题。 Blynk 提供的代码和错误消息如下: '''

BlynkESP8266_Lib 仅在 Release page 上的 Blynk 库的发布 zip 中可用。请参阅资产部分。

将文件夹 BlynkESP8266_Lib 从 zip 复制到速写本文件夹中的 libraries 文件夹中。 (草图文件夹的位置在 Arduino 的首选项对话框中设置 IDE。)
