ArduinoIoTCloudTCP::handle_SubscribeMqttTopics could not subscribe to /a/t/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/e/i In this case either the device has not been associated with the thing within the Arduino IoT Cloud GUI configuration or there's a typo in the thing ID....
Additionally, we need to inform the program of which rooms we want to monitor and how to connect to Arduino IoTCloud. For this purpose, create a file "config.json" with the following structure: { "iot_client_secret":"---your client secret here ---", "iot_client_id":"---your clien...
在这个物联网项目中,我展示了如何使用 ESP8266 Arduino 使用Arduino IoT Cloud和Alexa制作基于物联网的智能家居,以通过语音命令、红外遥控器和手动开关控制 4 台家用电器。 1 / 2 如果互联网不可用,您可以通过红外遥控和手动开关控制家电。 使用Alexa控制设备。 使用ArduinoEEPROM来记住以前的状态 用红外遥控器控制电...
在这个讲究万物互联的时代,让咱们的 Arduino 温湿度也去“云上”玩玩,有个学名叫物联网。 物联网(IoT) 是由物理对象组成的网络,这些物理对象嵌入了传感器、软件和其他技术,以便可以通过互联网与其他设备和系统建立连接并交换数据。 是不是瞬间感觉高大上了一些,但是不用担心本期的知识超纲,因为高深的我也不会!
