我尝试使用 Blynk 的桥小部件在 wi-fi 设备之间进行通信!
http://docs.blynk.cc/#widgets-other-bridge
目次
配置
A 部分
通过 wi-fi 将 nunchaku 控制器操纵杆的值发送到 blynk 服务器。
- wii nunchuck 控制器
- esp-wroom-02 开发板
- 电池模块
- 锂离子聚合物电池 400mAh
B 部分
接收发送到 Blynk 服务器的操纵杆值, 并移动 led 眼球。
- Neopixel 领导了68件作品使用
- 便宜的 esp8266 开发委员会
混合设置
创建两个项目并获取两个 auth 令牌。由于应用程序不是直接使用的, 因此根本不需要详细设置。
下面是阿杜伊诺的一个闪电侠图书馆。

arduino ide 程序
A 部分
下面的 wii nunchuck 库被用来连接到微型计算机。

B 部分
led 库使用了以下内容:

操作
使用 blynk, 您可以轻松地在设备之间进行通信!此外, 通信设置等。到服务器是不自觉的, 在所有容易
这是一个功能, 似乎传播各种可能性!
