新版 Ethernet W5100 網絡擴展板模塊 SD卡擴展 兼容UNO R3

2012最新版 Arduino Ethernet W5100 網路擴展板 SD卡擴展板 支持Mega328 Mega2560

 

Arduino Ethernet W5100網路擴展板，可以使Arduino成為簡單的Web伺服器或者通過網路控制讀寫Arduino的數位和類比介面等網路應用。可直接使用IDE中的Ethernet庫檔便可實現一個簡單Web伺服器。

同時該版本的支援mini SD卡（TF卡）讀寫

該擴展板採用了可堆疊的設計，可直接插到Arduino上，同時我們的其他擴展板也可以插上去。

 

IDE程式碼：

/*

* Web Server

*

* A simple web server that shows the value of the analog input pins.
