"All your device are belong to us"
In the last post of our Microsoft MVP Theme week, as all the MVP's start making their way home after a great, but brain filling week, we highlight Bryn Lewis, Microsoft MVP Embedded and awesome IoT teacher..
Last week I did a session about devices at Microsoft Ignite (Formerly TechEd) New Zealand.
I had a lot of kit on stage with 3 Netduinos, 3 Arduinos, and 2 Raspberry PI devices (running Windows 10 IoT Core) featuring in my 3 sets of demos.
This demo was about connecting sensors. I showed the different programing models used to read data from an ADXL345 accelerometer
Arduino Uno R3
Raspberry PI Windows 10 IoT Core
This was about hobbyist devices, wireless connectivity and cloud data services (I used Xively). I had 3 devices, two of which I passed into the audience for them to have a closer look at.
Netduino 3 Ethernet - Running my nRF24L01 Field gateway
devDuino 1.3 + temperature & Humidity sensor
devDuino 2.0 + temperature & Humidity sensor
An Azure ServiceBus EventHub (for telemetry) and a ServiceBus queue (for commands). My scenario was a vineyard managing frost fans to stop the crop getting damaged when it gets really cold.
Netduino 3 Wifi + DS18B20 temperature sensor uploading readings to an EventHub
Raspberry PI running Windows 10 IoT Core receiving messages from a queue and turning a small fan on/off
The code for Netduino 3 & RPI was built using Azure Service Bus Lite which worked really well.
I spent too much time preparing & testing but all my demos worked....
So much hype, so many different devices, so many protocols, so much data, so little security, welcome to the Internet of Things. Come and see how you can build an affordable, securable, scalable, interoperable, robust & reliable solution with embedded devices, Windows 10 IoT and Microsoft Azure. By 2020 there will be 26 Billion devices and 4.5 million developers building solutions so the scope is limitless.
