Learn how to build a text enabled robot that will take your beer order, serve your pint, and notify you when it is ready, all while keeping an eye on your consumption so that you wake up on time the next morning. In this demo-heavy workshop, we will use the Zipwhip Texterator as the platform on which we will show you how to use Alexa, AWS Lambda, and AWS IoT to build the ultimate beer serving device. AWS DevDay San Francisco, June 21, 2016. Presenter: John Rotach, SDE, AWS IoT

AWS IoT Workshop
AWS IoT + Alexa + Texterator = Beer
Featuring the Texterator from Zipwhip

3. Architecture Overview

4. Demo
http://bit.ly/28M9gFV

5. Let’s Build It
• Virtual ”Beer Me” Button App
• DynamoDB Rule
• Lambda for Alexa Skill
• SNS message publishing
Examples for this lab are found here:
http://bit.ly/28Qfvor
Prerequisites for this session are an AWS account and an Amazon Developer Account.

6. Virtual ”Beer Me” Button App
• Javascript, WebSocket MQTT Connection to AWS IoT
• Cognito Authentication
Code is in the examples.

7. Virtual ”Beer Me” Button App
Create a Cognito Identity Pool
• Important: Click box to enable unauthenticated users
• Name: BeerUsers

8. Virtual ”Beer Me” Button App
Policy document can be found in examples
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"iot:Connect"
],
"Resource": [
"*"
]
},
{
"Effect": "Allow",
"Action": [
"iot:Publish" ],
"Resource": [
"arn:aws:iot:us-east-1:<your account ID>:topic/devday/sfo/beers"
]
}
]
}
Attach a policy to the
unauthenticated role in IAM console

9. Virtual ”Beer Me” Button App
Test beer app using MQTT Client in AWS IoT Console

10. DynamoDB Table + Rule
AWS IoT Rule to insert beer requests into DynamoDB

11. DynamoDB Table + Rule
Create DynamoDB Table
• TableName: BeerRequests
• PartitionKey: PhoneNumber (String)
• No sort key
• Defaults and create

12. DynamoDB Table + Rule
Create AWS IoT Rule
• Create Rule in AWS IoT Console
• Create new role when prompted
SQL
select * from devday/sfo/beers
Action
DynamoDB
• Table Name: BeerRequests
• Hash Key: PhoneNumber
• Hash Key Value: ${phone}
• Hash Key Type: String

13. DynamoDB Table + Rule
Test with beer app and DynamoDB table viewer

14. SNS (Texterator)
• Create an SNS Topic
• Create an SNS Subscriber (SMS)
• SMS topic requires confirmation

15. Alexa Skill Overview
Alexa Skill Kit (requires Amazon Developer Account)
• Create a Lambda
• Signin with developer account
• Create a new Custom Skill
• Provide Lambda ARN
• Configure Interaction Model
• Test

16. Alexa Lambda
Create Lambda
• Create function (Alexa Skills must be in us-east-1)
• Create a new alexa-skills-kit-color-expert blueprint
• Edit code – paste in example
• Defaults for parameters
• Update execution role to add policy
• Requires access to DynamoDB, SNS
Lambda code and policy are in examples.

17. Alexa Lambda
Edit Lambda Code
• Ensure DynamoDB table name is correct
• Add SNS Topic ARN

18. Alexa Lambda
Sigin to Amazon Developer Console
• Create new Custom Skill
• Name: BeerApp
• Invocation Name: beer app
• Add intents schema
• Add utterances text
Schema and utterances are in the examples.
Invocation name is what the users will say:
“Alexa, ask beer app to pour the next beer”

19. Test End-to-End
Test using Alexa Device Simulator or Echosim.io
• Press ”beer me” button w/ phone numbers
• Tell Alexa to pour beer
• Receive SMS with selected number
• Degbugging info:
• CloudWatch Logs of Lambda Function
• Alexa Console

20. Thank You!
