Arduino と Ethernet Shield (micro SD, Wiznet W5100) 使ってみた

準備   
 ◆Arduinoソフト （PCにインストール無料）

◆Arduinoハード（ピンヘッダー同梱） （360円＋送料170）

◆Arduinoソフト（PC）と Arduinoハード をつなぐUSBケーブル（100円＋送料170円）

  

◆ Ethernet  Shield（870円＋送料170円）

◆ LANケーブル

◆Micro SD

工作開始

 １   Ethernet

◆(；￣Д￣)   Non-printed  MAC address (MACアドレス印刷されていない)

 local network ok, But  no internet（LANで使う分には問題ない、しかしWANで使うには登録必要と思う）

◆(；￣Д￣)

 (︶︹︺)

<(￣ ﹌ ￣)>

◆全てつなぎましょう

  

◆Arduinoソフトにスケッチを書きましょう

 

#include <SPI.h>
#include <Ethernet.h>

byte mac[] = { 0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02 };
EthernetClient client;

void setup() {
  Serial.begin(9600);
  if (Ethernet.begin(mac) == 0) {
    Serial.println("Failed to configure Ethernet using DHCP");
    for(;;)
      ;  // 永遠に何もしない
  }
  Serial.println(Ethernet.localIP());  // IPアドレスを表示
}

void loop() {
}

/*

  SD card test
  
 This example shows how use the utility libraries on which the'
 SD library is based in order to get info about your SD card.
 Very useful for testing a card when you're not sure whether its working or not.
    
 The circuit:
  * SD card attached to SPI bus as follows:
 ** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila
 ** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila
 ** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila
 ** CS - depends on your SD card shield or module.
         Pin 4 used here for consistency with other Arduino examples
