==Arduino可以做什麼？==
==Arduino那裏買==
*網路
**[http://www.playrobot.com/cart/index.php 飆機器人]
*網拍(奇摩、露天)
*淘寶
**淘寶是大陸最大的購物、商城網站，規模要比台灣任何一家電子購物、商城網站大上許多，我從淘寶一家[http://xdguo.taobao.com/shop/view_shop.htm?spm=a1z09.2.9.27.hy4bpV&user_number_id=132136629 信德電子]購入，總共花了約600人民幣，基本上一定比台灣買便宜很多，運費35元人民幣。(從大陸買東西便宜，台灣賣家多的是從對岸買進來再賣，天生比較喜歡冒險的人可以嘗試看看，從大陸寄貨回來時間約在二天，淘寶上的賣家也都蠻負責的。)

==Arduino第一步==
#下載Arduino驅動程式和開發軟體Arduino 1.0.4 ==> [http://arduino.cc/en/main/software http://arduino.cc/en/main/software], 解壓縮至硬碟 或從[https://docs.google.com/file/d/0BzE4m9IZwZhaZkhEZk5SY2RhZVk/edit?usp=sharing 我的google雲端硬碟]下載。

#使用USB連接上，將設備的驅動程式指向下載目錄中的drivers，成功抓取驅動程式後，系統的裝置硬體設定畫面為：
[[File:Arduino-COM.png|400px]]


COM7是Arduino透過USB驅動程式對Arduino單板的通訊連接埠號，程式之後都將以此COM7做為與Arduino單板之通訊基礎。(可能是其他的號碼，比方說是COM3。)

===實驗：RGB LED===
LED RGB呼吸燈~

藉由analogWrite([腳位],[亮度]);這個指令可以設定單一LED之亮度強弱，不過須在PIN端與LED相交處接上一支電阻降低電流。
digital IO 7 8 9 為三個不同顏色之PIN位，另一個接地

以下為原始碼

=pcDuino=
pcDuino是一個內嵌ubuntu Linux的實驗板，第一步要做的動作是要能連線到板子上的Linux作業系統，做法有二種：

#用HDMI線來連接LED螢幕
#透過網路連線到板子，有二個預設帳號，ubuntu/ubuntu，root/nopasswd，先用ubuntu帳號登入，下sudo sh切換至root，改變所有的預設密碼。
##使用ssh
##使用vnc，安裝x11vnc

  sudo apt-get install x11vnc
  sudo su
  cd /etc/ssh
  修改ssh_config檔案中的ForwardX11為yes
  x11vnc
