以w5100为核心的arduino ethernet网络扩展模块，可以使arduino成为简单的web服务器或者通过网络控制读写arduino的数字和模拟接口等网络应用。可直接使用ide中的ethernet库文件便可实现一个简单web服务器。 同时该版本的支持mini sd卡（tf卡）读写，功能强悍，不容错过！ 该扩展板采用了可堆叠的设计，可直接插到arduino上，同时我们的其他扩展板也可以插上去。 arduino ethernet网络扩展模块与arduino uno 控制器 arduino ethernet网络扩展模块与arduino mega2560控制器 ide中的实验代码： /* * web server * * a simple web server that shows the value of the analog input pi. */ #include byte mac[] = { 0xde, 0xad, 0xbe, 0xef, 0xfe, 0xed }; byte ip[] = { 192, 168, 0, 15 }; server server(80); void setup() { ethernet.begin(mac, ip); server.begin(); } void loop() { client client = server.available(); if (client) { an http request ends with a blank line boolean current_line_is_blank = true; while (client.connected()) { if (client.available()) { char c = client.read(); if we've gotten to the end of the line (received a newline character) and the line is blank, the http request has ended, so we can send a reply if (c == '\\n' && current_line_is_blank) { send a standard http respoe header client.println(/http/1.1 200 ok/); client.println(/content-type: text/html/); client.println(); output the value of each analog input pin client.print(/welcome to tinyos/); client.println(/ /); client.print(/*************************************/); client.println(/ /); client.print(www.tinyo); client.println(/ /); client.print(/*************************************/); client.println(/ /); for (int i = 0; i < 6; i++) { client.print(/analog input /); client.print(i); client.print(/ is /); client.print(analogread(i)); client.println(/ /); } break; } if (c == '\\n') { we're starting a new line current_line_is_blank = true; } else if (c != '\\r') { we've gotten a character on the current line current_line_is_blank = false; } } } client.stop(); } } "w5100网络扩展板"的机械刚性为柔性，型号是ewqwe1，层数为多层，基材是镍，品牌为13，加工定制是是，属性为jh
