This example shows how to divide a sensor's range into a set of four bands and to take four different actions depending on which band the result is in.这个例子显示如何分成一组四阶传感器的范围,并采取四种不同的行动,取决于频段的结果是英寸 Switch Case 2: a second switch-case example, ...
Web Client Example Modified version of the Ethernet shield's Web Client example. The HTTP response data cannot be printed out over USB serial as in original example, because it is already in use by the protocol. Instead it uses the software serial library to send it out over another serial...

(For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply ...
6.1 Client Server Socket connection using ESP8266-01 board 6.1 利用 ESP8266-01 板创建 Socket 连接 This lesson provide an example on how to receive message sent from a TCP Server, you'll need the following parts: 这一课是一个例子,让我们接受 TCP 服务器发过来的信息,你需要以下的零件: ...
// give the web browser time to receive the data delay(1); // close the connection: client.stop(); } } 让这个样例代码任务,附上一个一个按钮在 D2引脚和5V之间,一个10K电阻在 D2引脚与接地之间,然后负载你的ArduinoIP地址到你的网页浏览器。网页应当打开一个玄色的背景。按下这个按钮并保持住,然...

The example works like this: Arduino reads accelerometer Arduino sends JSON string of X,Y, and Z values to node.js node.js listens for clients If node.js gets a client, it reads serial string and generates a serialEvent, sending along the JSON object read from the Arduino ...
