The document outlines a project to build an open source home security system using Zetta, an open source platform for building Internet of Things applications. The project involves learning about Zetta and its development tools, building basic circuits with a buzzer and microphone, coordinating the devices using JavaScript, and exposing the system via API. Key steps included introducing IoT concepts, the Zetta platform for solving common IoT challenges, using Node.js and the BeagleBone Black for the system, and linking devices to allow external access.

- 6. Intro to the Internet of Things 6
- 7. • A growing ubiquitous network of devices. • Made up of Sensors and Actuators • Sensors – Sense the world around you. – Report data back • Actuators – Act on the world around you – Give feedback The Internet of Things
- 8. • Data – What to store? – What to use? • Interfaces and Protocols – Many protocols exist for IoT? – What to use? • Devices in large systems – How to coordinate devices in large systems? • Quality of Tooling – How to build tools for people building products? Issues within the Internet of Things
- 9. Zetta is an open source platform for the Internet of Things. It harnesses JavaScript to make things quick and easy. Zetta tackles all these problems in an elegant, and efficient way. Intro to Zetta
- 10. • Data – Broadcasting data over websockets. – Make collection and analysis easy • Interfaces and Protocols – Use HTTP to communicate with devices – Every device gets an API generated from Node.js • Devices in large systems – Coordinate devices across the globe with ease • Quality of Tooling – Designed with the developer in mind – Multiple tools for helping develop quickly Solving these problems
- 11. Intro to our Technology 11
- 12. • Evented and Async • Open source • Every developer knows JavaScript • Can run on many different platforms Why Node.js?
- 13. • Single board computer, runs Linux and similar to Raspberry Pi • Low cost and community supported • Comes with Node.js pre-installed • Has a node module for accessing hardware • Browser based IDE for programming right on the board Why BeagleBone Black?
- 14. • Tool for prototyping electronic circuits • Great for circuits without soldering Intro to Breadboard
- 15. • Create a new file to put some code in Getting Started
- 16. Let’s write a snippet of Zetta and see what happens! Writing some Zetta code

- 22. Linking 22
- 23. 23 ©2015 Apigee. All Rights Reserved. Problem: How do we expose our API to the world?
- 24. What does linking do? 24 ©2015 Apigee. All Rights Reserved. Z1 Z2 F i r e w a l l Tunneled Connection HTTP Request Linking creates a secure tunnel out of home networks allowing you to expose your API to the world.
- 25. • Built an open source security system • Our process a. We learned how to use Zetta b. We learned about it’s development tools and best practices c. We built circuitry to power our system d. We coordinated these devices using JavaScript and interacted with them via API. • We Learned a. How to create basic circuits b. How to work with the BeagleBone Black c. Harnessing the Zetta toolchain Our Completed Project - Home Security
