3. What is the Internet of things
   The Internet of things refers to uniquely identifiable objects and their virtual representations in an
   Internet-like structure. Kevin Ashton proposed the term Internet of things in 1999, though people
   have discussed the concept since at least 1991.

   

   Today however, the term Internet of things (commonly abbreviated as IoT) denotes advanced
   connectivity of devices, systems, and services that goes beyond the traditional M2M and covers a
   variety of protocols, domains and applications.

4. What is NodeJS
   Node.js is a software platform for scalable server-side and networking applications. Node.js applications
   are written in JavaScript, and can be run within the Node.js runtime on Windows, Mac OS X and Linux
   with no changes.

5. Arduino is a single-board microcontroller, intended to make the application of interactive objects or
   environments more accessible.

   Introduced in 2005, it was designed to give students an inexpensive and easy way to program interactive
   objects. It comes with a simple integrated development environment (IDE) that runs on regular personal
   computers and allows to write programs for Arduino using C or C++.

6. Salesforce1 is a mobile app development platform for everyone. It allows incredible freedom for ISVs,
   developers, administrators, and every user to innovate.
   !
   This approach to unlocking mobile app development for organizations is built for today’s needs: mobile
   and social solutions delivered in days or weeks.
   !
   Designed for scale with open APIs for extensibility and integration, and powerful developer tools, there’s
   no limit to what developers and ISVs can build on the platform.

7. This project
   ▪ Control lights remotely using SF1
   ▪ Know when somebody is ringing the bell at the office

9. Salesforce
   ▪ Created a custom object called "Light"

   - This object has 2 fields "State" and "PIN"
   PushTopic pushTopic = new PushTopic();
   pushTopic.Name = 'LightStateChanges';
   pushTopic.Query = 'SELECT Id, Name, State__c, PIN__c FROM Light__c';
   pushTopic.ApiVersion = 30.0;
   pushTopic.NotifyForOperationCreate = true;
   pushTopic.NotifyForOperationUpdate = true;
   pushTopic.NotifyForFields = 'Referenced';
   insert pushTopic;
   ▪ Created a Streaming Push Topic to monitor changes on the object:

10. NodeJS
    ▪ Interaction with the Arduino is made using Johnny Five

    URL: https://github.com/rwaldron/johnny-five

    What it does: 

    Establishes a connection with the Arduino through USB, can interact with connected
    components in real time.

    ▪ Interaction with Salesforce is made using NForce

    URL: https://github.com/kevinohara80/nforce

    What it does:

    Connects to Salesforce using credentials and interacts with all APIs available
    including force.com Streaming API.

11. NodeJS
    ▪ Connects to our salesforce instance using NForce.
    ▪ Subscribes to our force.com Streaming PushTopic LightStateChanges
    ▪ Establish a connection with the Arduino
    // When the Arduino board is ready and connected
    board.on("ready", function(){
    // nforce Authentication
    org.authenticate({ username: '', password: '' },
    function(err, oauth) {
    // subscribe to a pushtopic
    var str = org.stream({ topic: 'LightStateChanges', oauth: oauth });
    str.on('data', function(data) {
    // interacts with the data received when a record changes ....
    });
    });
    });

14. Chatter
    ▪ Interacting with the Arduino through chatter
    ▪ Created a chatter group called Office
    gadgets
    ▪ Created a trigger on FeedItem object and
    look for the commands 

    !lightsON and !lightsOFF to change our
    lights state.

15. Let's connect something else!
    Power pins
    Button
    Chatter in SF
    Digital pins
    

    View Slide

16. NodeJS
    // Instantiate button (pin 8)
    button = new five.Button(8);
    // when the button is pressed...
    button.on("down", function() {
    !
    // create a chatter post (FeedItem)
    var post = nforce.createSObject('FeedItem');
    post.set('Body', 'DING-DONG! Somebody is at the front door ringing the bell.');
    post.set('ParentId','0F9i0000000LNqZ');
    !
    org.insert({ sobject: post, oauth: oauth }, function(err, resp){
    if(err) console.log(err)
    });
    });
    Every time the button is pressed a FeedItem is created using NForce

17. Adding a sensor
    Analog pins
    Power pins
    Chatter in SF
    Photoresistor
    

    View Slide

18. NodeJS
    // LIGHT SENSOR HANDLING
    photoresistor = new five.Sensor({
    pin: "A5",
    freq: 250,
    threshold: 100
    });
    !
    // "data" get the current reading from the photoresistor
    photoresistor.on("change", function() {
    if(this.value < 300 ){}
    if(this.value > 600 ){}
    });
    When the voltage readings of the photoresistor hit certain values a chatter message
    is created to turn lights on or off.
