Are you a developer who wants to learn about the Internet of Things (IoT)? Do you want to retrieve data from Internet-connected sensors for applications in home automation, healthcare, automotive, government and more? Do you want to control sensors and devices remotely from cloud, mobile, or desktop applications? In the IoT Fire Starter workshop you will use an IoT prototyping kit (that is yours to keep) to learn how to create micro-controller devices (the ‘Things’ in IoT) that use a variety of physical sensors such as light and temperature sensors; control switches; servos; and motors. You will learn how to connect these Things to Microsoft Azure IoT services to both collect data and issue control commands to the devices. Once you have mastered prototyping the hardware and connecting it to the Cloud, you will learn how to leverage Azure IoT services to gain insight into the data coming from your connected Thing, including analytics and machine learning. Following the workshop you will be able to continue your experience with your prototyping kit by following additional hands-on labs you can subscribe to online. You will need to bring your own laptop for this workshop.

https://build.particle.io/signup
• Create a Microsoft Azure Trial Account
https://azure.microsoft.com/en-us/pricing/free-trial/

12. MAKER 101
The fundamentals of maker development kits

13. LAB 01: WRITING DIGITAL OUTPUT
The ‘Hello, World!’ of devices

14. BILL OF MATERIALS
• Particle Photon
• USB to micro-USB cable (there is one included in the Photon
Development Kit)
• LED (there is one included in the Photon Development Kit)
• 220-Ohm 1/4 Watt resistor (there is one included in the Photon
Development Kit)

15. CLAIM YOUR PHOTON
• Apple iPhone or Google Android – Use Particle Tinker App
• Windows PC –
• Download and install Photon drivers –
https://s3.amazonaws.com/spark-website/Spark.zip
• From Node.js Command Prompt:
particle identify (copy the device ID)
particle serial wifi (scan and select the Wi-Fi network)
(Wait for Photon to restart)
particle device add YOUR_DEVICE_ID_HERE

16. UPLOAD THE VOODOOSPARK FIRMWARE
• https://build.particle.io
• Create a new app named VooDooSpark
• Copy the code from http://tinyurl.com/VooDooSpark
• Target your Photon
• Validate the code
• Flash the Photon

17. OHM'S LAW
• Voltage = current (in amps) x resistance
• V = IR or R = V/I or I = V/R
• Resistance (R) = Voltage (V) / Current (I)
• R = 5V / 15mA (1,000 milliamps = 1 amp)
• R = 5 / .015
• R = 333.333 Ohms (330 Ohms is close enough)
• R = 5V / 10mA
• R = 5/.01
• R = 500 Ohms (560 Ohms is close enough)

• isRelevant – should I care about the message?
• Message type is _lightState or _lightLevel and
the message is either from or to this device ID
• isCommand – do I need to execute the message?
• Message type is _lightLevel
• obsoletes – do I care any more? (e.g. have I already processes this)
• Does the CommadManager think this is obsolete?
• Is the downstream message _lightState, and
is it in response to the specified upstream message, and
is the upstream message type _lightLevel
• executeQueue – do whatever needs to be done based on the message
• Iterate the activeCommands and perform some action
• start – get things going
• Starts the CommandManager, gets all the messages and subscribes to future messages
