A working prototype of an Alexa skill was created and uploaded to GitHub. Uploaded files include the current Intents Schema, Sample Utterances, Slots, and the Lambda JavaScript function that makes the HTTPS POST and GET connections to the Particle Photon in the Wall Switch.

As is, it is a good proof of concept. Using the Alexa utterances test section of developer.amazon.com, communication from Alexa to the Lambda function (located at console.aws.amazon.com) to the Photon and back to the Alexa work.

The JavaScript POST and GET functions embedded within the Lambda function that connect Lambda to a Particle Photon are working. Though it works, I have not quite mastered the intent schema and sample utterances syntax yet though so at least that will need be updated.
