如果连接成功,说明Arduino已经与网页服务器建立了通信通道。 client.println() 是用来向服务器发送HTTP请求,GET / HTTP/1.1表示请求根路径(/)的内容,使用HTTP 1.1协议;Host: http://www.google.com指定目标主机名;Connection: close告诉服务器在响应完成后关闭连接。 请求完成,我们可以使用如下方式查看服务器响应内容...
ESP8266module is not 5V tolerant. It works on 3.3V power suplay. Most Arduinos works on 5V. If we want connect both components we need to adapt voltage levels between. If you are using 3.3V Arduino, then readESP8266 WiFi and 3.3V Arduino connection. First we need 3.3V power supply f...
If you are trying to add Wifi connectivity to an existing Arduino project or have serious aspirations for developing a Internet of Things (IoT) solution, Arduino + ESP8266 wifi module is one of the top choices. Especially the Nano because it is super cheap (<$3) and is very small in ...
