IOT(Internet of Things) Using Arduino MCU ABC - Session 2
Arduino MCU(8/16 位元微型控制板), 是義大利開發的
開放原始碼(open source)
的軟硬體平台, 所以有很多國家的工廠在生產, 同樣規格或變更/加強 Arduino 原始規格的微型控制(MCU)電子元件/線路的複製或改良的微控制板(MCU).
由於使用者的不同實驗目的或生產產品的功能定位, 所以Arduino AVR 有一系列的不同規格的微型控制板(MCU), 大概可分為以下幾種系列 Uno, Mega2560, Duemilanove, Mega, or Diecimila ..等(請參考原廠的 MCU & Accessory Series 介紹, 其網址如右所示: Arduino.cc Hardware Reference):

Arduino MCU 區分了如此多的系列, 無非就是考量終端使用者的使用需求, 有些人需要外接的
控制元件的多寡
Arduino 的控制程式語言使用了類似 Java，C 語言的 Arduino Programming Language(Base on Processing / Wiring) 開發環境, 閣下可以使用官方的 Arduino IDE 程式控制碼編
譯軟體來編譯及下載到微控制板上(**不過有些微形控制板(MCU)是無法被直接下載已經編譯
的程式碼, 還需經過 RS-232 <-> USB 的線路轉換後, 才能從 Arduino IDE 下載至 MCU 上).
