ABOUT THIS COURSE

In this hands-on Internet of Things (IoT) course, you'll build Node-RED flows (applications) running on the cloud and connect them to more flows and Swift applications. You'll use those applications to track the temperature of a Raspberry Pi CPU, store that data in a Cloudant NoSQL database, take pictures with the RaspCam, use AI to recognize objects in the pictures, send Twitter notifications, and send simple commands from your smartphone to the iRobot.

Important: You don't need to purchase the iRobot to be successful in this course. But playing with a programmable robot can be a lot more fun!


COURSE OUTLINE

  • Lab 1: Read temperature data from an IoT sensor
    • Lab 1 application architecture
    • 1. Create the Internet of Things Platform Starter and connect to a virtual sensor
    • 2. Prepare the Raspberry Pi to use as an input source
    • 3. Connect the Raspberry Pi Node-RED flows to IBM Cloud
    • 4. Optional: add social media notifications to your flow
    • 5. Add a Cloudant database to store temperature data
    • 6. Create a UI in Swift and Xcode
    • Lab 1 quiz
  • Lab 2: Add a camera and analyze images
    • Lab 2 application architecture
    • 2. Invoke a Node-RED flow on the Raspberry Pi from the Node-RED flow
    • 3. Analyze an image from Raspberry Pi on IBM Cloud
    • 4. Add a Cloudant database node
    • 5. Retrieve and analyze a picture on IBM Cloud
    • 6. Retrieve the picture that was taken by the Raspberry Pi in a Swift application
    • Troubleshooting connection problems
    • Lab 2 quiz
  • Lab 3: Connect your app to an iRobot and smartphone
    • Lab 3 application architecture
    • 1. Create a device schema on the Internet of Things Platform service
    • 2. Invoke the MQTT command on Watson IoT Platform from the iOS application
    • 3. Optional: Connect your application to the iRobot
    • 4. Add a voice user interface
    • Lab 3 quiz
  • Final exam

PREREQUISITES

You must have programming experience with Node-RED, IBM Cloud, Raspberry Pi, Swift, iOS, and Cloudant databases.

You'll need the following accounts, software, and hardware:

You can complete Lab 2 without purchasing a camera. Instead of using the camera, you'll use images from the Internet, but using a camera is a lot more fun!
