+==== Step #3: Load Arduino Sketch ====

+Download the the IR library. (This library is a fork I created of the excellent Arduino IRremote library created by Ken Shirriff.)
+Unzip the archive, rename the folder from Arduino_IRremote-master to Arduino_IRremote, and import the Arduino_IRremote folder as a library into your Arduino IDE. Check out this guide for more information on installing libraries.
+Download the Smart Remote Control Arduino sketch by grabbing the zip file from this location.
+Uncompress the archive and drag the SmartRemoteControl folder into your Arduino sketchbook folder. Open the sketch in the Arduino IDE.
+Compile the sketch and upload it to the Yún over WiFi by selecting the 'Arduino Yún at ...' option in the port list. Make sure to upload the sketch over WiFi so the necessary python scripts are copied to the Yún! Once the sketch has uploaded, open the Serial Monitor in the Arduino IDE. (Be patient, the first upload can take a few minutes.)
+Aim a remote control at the IR sensor and press a few buttons on the remote. You should see IR code information displayed in the Serial Monitor. If you don't see codes displayed, double check your sensor wiring.
+==== Step #4: Configure Remote Control Codes ====
+{{:2016:screen-shot-2014-06-13-at-11-13-43-pm.png?300|}}
+  * You can now configure the activities and remote control codes associated with them by editing an XML configuration file. Using a text editor, open the activities.xml file in the www subdirectory of the sketch's folder on your computer. (From the Arduino IDE, click the Sketch menu and then select "Show Sketch Folder.")
+  * Notice the format of the example activities in the file. Each activity node defines a name attribute which will be displayed as a button on the remote web page. Within each activity, the codes node contains a sequence of IR codes to execute. The example activity will first execute a Sony A90 command (power on/off) to turn on the TV, and then a Panasonic command (power on/off) to turn on the Blu-ray player. Each code has a string value which is the direct output of the detected remote code from the Arduino sketch.
+  * Add your own activities to the file by copying the example and changing the name and codes. While your remote is aimed at the IR sensor, press buttons and carefully record the detected IR code string. Copy the string into the activity code configuration.
+  * Once you're happy with the activity configuration, save the file and upload the sketch to the Yún again using WiFi. Each time you want to update the activity configuration, change the file and upload the sketch over WiFi using the Arduino IDE.
+==== Step #5: Start Web Interface Server ====
+{{:2016:screen-shot-2014-06-13-at-11-02-32-pm.png?300|}}
+  * To run the server, connect to the Yún over SSH. Execute the following command to start the server:
+<code>
+python /mnt/sda1/arduino/www/SmartRemoteControl/server.py
+</code>
+  * If the server starts successfully you should see the following text:
+<code>
+  Running on http://0.0.0.0:5000/
+  Restarting with reloader
+</code>
+  * If you see an error, check that all the required dependencies were installed in the previous steps.
+  * In a web browser, navigate to the URL http://arduino.local:5000/. If your browser doesn't support mDNS URLs (like Windows, Android, and some Linux distributions) instead access http://arduino_ip_address:5000/ where arduino_ip_address is the IP address of your Arduino Yún. The IP address can be found at the bottom of the Arduino IDE when the Yún is connected (image 2).
+  * Once the page is loaded, you should see a list of the configured activities as buttons. If you see an error, check that dependencies were installed properly, the sketch was uploaded, and the server is running without errors.
+  * To stop the server, press Ctrl-C in the command window where you started running the server.
+==== Step #6: Use Web Interface ====

+  * To use your smart remote control, aim the LED at your electronic devices and press one of the activity buttons. If you don't see all your expected devices turn on, try moving the LED closer to the devices. The range of the LED can be somewhat small, around 6 feet of distance. You can consider adding a transistor to increase the LED range as well.
+  * You can also test IR codes by opening the Yún Serial Monitor in the Arduino IDE and sending the IR code as a command. For example, sending "SONY: C A90" (without quotes) would cause the hardware to send a Sony A90 power command. (The "C" above represents the bit length of the command, 12, converted to hexadecimal.)
+  * To make the server automatically start on boot, edit the file /etc/rc.local on the Yún (using a text editor such as nano or vi) and add the following line before the "exit 0" line at the end:
+   PYTHONPATH=/mnt/sda1/python-packages python /mnt/sda1/arduino/www/SmartRemoteControl/server.py
+  * To use speech recognition, make sure you're running the Google Chrome web browser. Click the 'Speak' button and Chrome should ask for your permission to listen to the microphone. Once you allow microphone permission, say the name of an activity and wait a moment to see if the activity was recognized. For example, to play the 'Movies' activity, click the 'Speak' button, allow microphone access, and say the word 'Movies'. Phrases like 'Play Movies' or 'Run Movies' unfortunately aren't supported — only the exact activity name will be recognized.

-Restart your Arduino Yún to make sure the Python search path is updated.
