We have chosen two variables to trigger music selections in a coded playlist. Temperature and light (time of day) will be sensed using the Grove light and temperature senors which are hooked up to the Intel Edison board. Corresponding results from the sensors will trigger a request to youtube with the specific songs playing on Android phone.
Some examples include; Relaxing Morning song from time of sunrise and low to mid temperatures, Fireplace crackling sounds during very cold temperatures (throughout the day), and upbeat Lindsey Stirling songs throughout mild to hot temperatures and brighter light.
This has been an attempt to capture emotion that may be present during various times of day with light, and temperature.

A simple node.js application intended to read data from Analog pins on the
Intel based development boards
such as the Intel(R) Galileo and Edison with Arduino breakout board, and
display it in a browser running on the client.
This demonstrates use of http.createServer, and fs.
MRAA - Low Level Skeleton Library for Communication on GNU/Linux platforms
Library in C/C++ to interface with Galileo & other Intel platforms, in a
structured and sane API with port nanmes/numbering that match boards &
with bindings to javascript & python.
Steps for installing MRAA & UPM Library on Intel IoT Platform with
IoTDevKit Linux* image
Using a ssh client:
1. echo "src maa-upm http://iotdk.intel.com/repos/1.1/intelgalactic" >
/etc/opkg/intel-iotdk.conf
2. opkg update
3. opkg upgrade
