What is Arduino?
• Open Source + Software IDE + Community
Hardware
What is for today?
• 接收紅外線訊號
• A Simple DIY IR Decoder
• 發射紅外線訊號
• DIY Keypad Remote Control
Infrared Remote Control
• 非常普遍使用的無線通訊
• 用於電視、冷氣、DVD Player、MP3 Player, 玩具遙控車等各種設備的控制
Arduino & IRRemote
• With Arduino & IRRemote Library, you can make your own infrared applications.
What you need?
• First, you need an Arduino board and an USB cable
What you need?
• Second, you need Arduino IDE to write program
What you need?
• Third, an infrared receiver and a 940 nm Infrared LED (a.k.a Infrared Emitter)
What you need?
• Last, download and install IRRemoteLibrary: http://goo.gl/2HKLm
Make sure things work
• Load "File > Examples > 1.Basics > Blink"
Examples used in this opentalk
• For your convenience, the examples used in this opentalk has been uploaded to google doc, you can download the examples from the following url:

接收紅外線訊號
• The wiring:
接收紅外線訊號• Load "File > Sketchbook > IRRemoteExamples > Example1_1"
接收紅外線訊號
• Try your remote:
接收紅外線訊號
• Open Serial Monitor and see the result:
Four steps to receive Infrared signals
1. 引用 IRRemote 函式庫:#include <IRremote.h>
2. 建立 IRrecv 物件及 decode_results變數:const int irReceiverPin = 2; // 紅外線接收器 VOUT 腳位
IRrecv irrecv(irReceiverPin); // 用來接收紅外線訊號
decode_results results; // 用來存放解碼結果
3. 啟動紅外線解碼:irrecv.enableIRIn(); // 啟動紅外線解碼
4. 檢查有沒收到紅外線:if (irrecv.decode(&results)) { // 解碼成功…

• Load "File > Sketchbook > IRRemoteExamples > Example1_2"
顯示紅外線協定種類
• Open Serial Monitor and see the result:
Infrared LED Indicator• Load "File > Sketchbook > IRRemoteExamples > Example1_3v2"
Infrared LED Indicator
• The infrared LED indicator will blink when infrared signal is received.

發射紅外線訊號• The wiring (IR LED 一定要接在 pin 3):
發射紅外線訊號• Load "File > Sketchbook > IRRemoteExamples > Example2_1"
Three steps to send Infrared signals
1. 引用 IRRemote 函式庫:#include <IRremote.h>
2. 建立 IRsend 物件:IRsend irsend; // 定義 IRsend 物件來發射紅外線訊號
3. 呼叫對應的 sendXXX() 函式發射紅外線訊號:irsend.sendNEC(0x4FB48B7, 32); // 記得換成你的紅外線編碼
DIY Keypad Remote Control• http://coopermaa2nd.blogspot.com/2011/04/22-keypad.html
