Console Pixel
An example of using the Arduino board to receive data from the
Console on the Arduino Yun. In this case, the Arduino boards turns on an LED when
it receives the character 'H', and turns off the LED when it
receives the character 'L'.
To see the Console, pick your Yún's name and IP address in the Port menu
then open the Port Monitor. You can also see it by opening a terminal window
and typing

SD card datalogger
This example shows how to log data from three analog sensors
to an SD card mounted on the Arduino Yún using the Bridge library.
The circuit:
* analog sensors on analog pins 0, 1 and 2
* SD card attached to SD card slot of the Arduino Yún
Prepare your SD card creating an empty folder in the SD root
named "arduino". This will ensure that the Yún will create a link
to the SD to the "/mnt/sd" path.
You can remove the SD card while the Linux and the
sketch are running but be careful not to remove it while
the system is writing to it.

ControlBySMS
Demonstrates using an SMS message to a Twilio account to turn an LED
on the Yun board on and off using the Temboo Arduino Yun SDK.
Sending a SMS with the text "LED ON" to your Twilio phone number
will turn on the LED on the Yun. Sending "LED OFF" will turn it off.
Check out the latest Arduino & Temboo examples and support docs at http://www.temboo.com/arduino
A Temboo account and application key are necessary to run all Temboo examples.
If you don't already have one, you can register for a free Temboo account at
http://www.temboo.com
Since this sketch uses Twilio to retrieve the SMS, you'll also need a valid
Twilio account. You can create one for free at https://www.twilio.com.
The sketch needs your Twilio Account SID and Auth Token you get when you
register with Twilio. Make sure to use the Account SID and Auth Token from
your Twilio Dashboard (not your test credentials from the Dev Tools panel).
Normally, Twilio expects to contact a web site you provide to get a response
when an SMS message is received for your Twilio number. In this case, we
don't want to send any response (and we don't want to have to set up a web
site just to receive SMS messages.) You can use a URL that Twilio provides
for this purpose. When a message is received and sent to the Twilio "twimlets"
URL, it returns a code meaning "no response required." To set this up:
1. Log in to your Twilio account and go to this URL:
https://www.twilio.com/user/account/phone-numbers/incoming
2. Select the Twilio number you want to receive SMS messages at.
3. Put this URL in the "SMS Request URL" field:
http://twimlets.com/echo?Twiml=%3CResponse%3E%3C%2FResponse%3E
See this link to Twilio's FAQ for details:
https://www.twilio.com/help/faq/sms/how-can-i-receive-sms-messages-without-responding
4. Click the "Save Changes" button at the bottom of the page.
Your account will now receive SMS messages, but won't send any responses.
This example assumes basic familiarity with Arduino sketches, and that your Yun is connected
to the Internet.

SendAnSMS
Demonstrates sending an SMS via Twilio using Temboo from an Arduino Yun.
Check out the latest Arduino & Temboo examples and support docs at http://www.temboo.com/arduino
A Temboo account and application key are necessary to run all Temboo examples.
If you don't already have one, you can register for a free Temboo account at
http://www.temboo.com
Since this sketch uses Twilio to send the SMS, you'll also need a valid
Twilio account. You can create one for free at https://www.twilio.com.
The sketch needs your Twilio phone number, along with
the Account SID and Auth Token you get when you register with Twilio.
Make sure to use the Account SID and Auth Token from your Twilio Dashboard
(not your test credentials from the Dev Tools panel).
Also note that if you're using a free Twilio account, you'll need to verify
the phone number to which messages are being sent by going to twilio.com and following
the instructions under the "Numbers > Verified Caller IDs" tab (this restriction
doesn't apply if you have a paid Twilio account).
This example assumes basic familiarity with Arduino sketches, and that your Yun is connected
to the Internet.
Looking for another API to use with your Arduino Yun? We've got over 100 in our Library!
This example code is in the public domain.

SendDataToGoogleSpreadsheet
Demonstrates appending a row of data to a Google spreadsheet using Temboo from an Arduino Yun.
Check out the latest Arduino & Temboo examples and support docs at http://www.temboo.com/arduino
A Temboo account and application key are necessary to run all Temboo examples.
If you don't already have one, you can register for a free Temboo account at
http://www.temboo.com
Since this sketch uses a Google spreadsheet, you'll also need a
Google account: substitute the placeholders below for your Google account values.
This example assumes basic familiarity with Arduino sketches, and that your
Yun is connected to the Internet.
The columns in your spreadsheet must have labels for the Choreo to
work properly. It doesn't matter what the column labels actually are,
but there must be text in the first row of each column. This example
assumes there are two columns. The first column is the time (in milliseconds)
that the row was appended, and the second column is a sensor value.
In other words, your spreadsheet should look like:
Time | Sensor Value |
------+-----------------
| |
NOTE that the first time you run this sketch, you may receive a warning from
Google, prompting you to authorize access from a 3rd party system.

IMPORTANT NOTE: TembooAccount.h:
TembooAccount.h is a file referenced by this sketch that contains your Temboo account information.
You'll need to edit the placeholder version of TembooAccount.h included with this example sketch,
by inserting your own Temboo account name and app key information. The contents of the file should
look like:
#define TEMBOO_ACCOUNT "myTembooAccountName" // your Temboo account name
#define TEMBOO_APP_KEY_NAME "myFirstApp" // your Temboo app key name
#define TEMBOO_APP_KEY "xxx-xxx-xxx-xx-xxx" // your Temboo app key
You can find your Temboo App Key information on the Temboo website,
under My Account > Application Keys
The same TembooAccount.h file settings can be used for all Temboo SDK sketches.
Keeping your account information in a separate file means you can share the main .ino file without worrying
that you forgot to delete your credentials.

Temperature web interface
This example shows how to serve data from an analog input
via the Arduino Yún's built-in webserver using the Bridge library.
The circuit:
* TMP36 temperature sensor on analog pin A1
* SD card attached to SD card slot of the Arduino Yún
Prepare your SD card with an empty folder in the SD root
named "arduino" and a subfolder of that named "www".
This will ensure that the Yún will create a link
to the SD to the "/mnt/sd" path.
In this sketch folder is a basic webpage and a copy of zepto.js, a
minimized version of jQuery. When you upload your sketch, these files
will be placed in the /arduino/www/TemperatureWebPanel folder on your SD card.
You can then go to http://arduino.local/sd/TemperatureWebPanel
to see the output of this sketch.
You can remove the SD card while the Linux and the
sketch are running but be careful not to remove it while
the system is writing to it.

Arduino Yun USB-to-Serial
Allows you to use the Yun's 32U4 processor as a
serial terminal for the linino processor.
Upload this to an Arduino Yun via serial (not WiFi)
then open the serial monitor at 115200 to see the boot process
of the linino processor. You can also use the serial monitor
as a basic command line interface for the linino processor using
this sketch.
From the serial monitor the following commands can be issued:
'~' followed by '0' -> Set the UART speed to 57600 baud
'~' followed by '1' -> Set the UART speed to 115200 baud
'~' followed by '2' -> Set the UART speed to 250000 baud
'~' followed by '3' -> Set the UART speed to 500000 baud
'~' followeb by '~' -> Sends the bridge's shutdown command to
obtain the console.
