  • Blog Post: Arduino Netduino Spark.IO: Building a Win 8 app that consumes Spark.IO output part 2: Model View Controller sort of

    These blog entries will jump about as I write them, if you are a regular reader then you understand, if you just dropped in from the internetosphere, then it will seem a little jumpy.  In fact if you just jumped in from the internetosphere for the first time,  then you need to read the disclaimer...
  • Blog Post: Arduino Netduino Spark.IO: Building a Win 8 app that consumes Spark.IO output part 1: Class Diagram

    Note to Cordana: Find out how to extend the Main title before the punctuation symbol colon… Building an Windows 8 app to consume the Spark Core generated javascript/ecmascript, might be a little scary, there are two languages involved, processing.io and C#.  Also, you have to get your Spark connected...
  • Blog Post: Arduino Netduino: Spark.IO Windows 8 App

    Thanks to Jerry Nixon for his assistance in turning an otherwise awful app into one that shines, as well morphing it into a Model View thing.  You will need to flash this code into your Spark.io device (for those readers not familiar with the Spark, check it out, super cheap for the WiFi capabilities...
  • Blog Post: Arduino Netduino: Oscilloscope and Logic Analyzer

    I have been thinking about buying a nice Oscilloscope/Logic Analyzer ever since I bought that little cheapie one I bought a few weeks ago.  But then I thought that it would be cool to build one.  I know how they work, and usually my needs are pretty low tech and low bandwidth.  As a result...
  • Blog Post: Arduino Netduino: Collecting the sensor data and displaying it using Excel

    In my previous blog: Arduino Netduino- Hall Effect Transistor and Circuit connected to the Arduino   and the blog before the first one (or former): Arduino Netduino- Hall Effect Switches, Keyes 003 Magnetic Sensor   We were able to get the Hall Effect Switch working and to see how we could...
  • Blog Post: Arduino Netduino: Hall Effect Transistor and Circuit connected to the Arduino

    Using the circuit described in a previous blog post: http://blogs.msdn.com/b/devschool/archive/2014/06/16/arduino-netduino-keyes-key-switch-module.aspx Switch the wire on post 1 that connects to the port D2 on the Arduino from the switch to the working Hall Effect device Pin 3.  Now run the previously...
  • Blog Post: Arduino Netduino: Hall Effect Switches, Keyes 003 Magnetic Sensor

    In the Sunfounder sensor treasure chest of 37 sensors, there are a number of simple switches, relays and so forth, and the Hall Effect is one of these sensors, but it’s different.  Most of the sensors uses some sort of change in resistance, but the Hall Effect is quite a bit different, it uses a...
  • Blog Post: Arduino Netduino: Hall Effect, Keyes 003 Magnetic sensor and the General Theory of Electromagnetism

    Hall Effect or Magnetic ring, in my blogs I have discussed both, and both of these devices detect magnetic fields.  As you may know, from Maxwell’s General Theory of Electromagnetism, we discover that many professors struggle with making electromagnetism fun!  Ok, that wasn’t the point, if...
  • Blog Post: Arduino Netduino: Keyes KY003 Hall Effect Transistor in Sunfounder kit, the real deal

    Well it has always been tricky to get circuits to work, but the information can be difficult to figure out and with kits like the Sunfounder you are go to find pin-outs are not correct.  After a few hours of study, I figured out how to make the KY003 or 03 KEYES Arduino Hall Magnetic Sensor Module...
  • Blog Post: Arduino Netduino: Keyes Key Switch Module

    All right this is an easy one, it is just a switch, with a resistor, just like the previous sensor blog, except this one is activated by someone or something pushing it.  What about that Magnetic Hall effect transistor lab, well, that sensor looks like another sensor, and the output is odd, might...
  • Blog Post: Arduino Netduino: Consider the Spark.IO, lots of low cost configurations

    Got to love the Spark.IO device, which I have been ignoring while I worked with the UNO and Netduino boards, mainly because the use of Wi-Fi, while cool is not really an option in large events.  And a large event is anything that jams the local Wi-Fi transceivers.  This jamming happens at most...
  • Blog Post: Arduino Netduino: What does it cost to use the Microsoft Cloud/Azure Service Bus?

    If you have an MSDN (not MSDNAA or DreamSpark) subscription, then you get the level of support provided by MSDN, it will likely vary so I won’t quote the monthly amount available.  (Ok, it’s $150 per month provided to you for no cost on 6/12/2014.) So here is the cost for messages, and we will be...
  • Blog Post: Arduino Netduino: Bluetooth test findings

    I could NOT get that Bluetooth JY-MCU to work, until I used the 5 volts not the 3.3 volts.  Got that.  The voltage range for the JY-MCU is 3.6 to 6 volts, which means that 3.3 volts is not equal to 3.6 volts.  Duh! To help with the troubleshooting as I stated I simplified everything and...
  • Blog Post: Insteon for Hub: Thoughts about building Arduino creations that work with the Insteon for Hub

    Check it out! You could get in on the positive momentum with the Insteon on Hub app in Windows 8. The app can be found at: http://apps.microsoft.com/windows/en-us/app/77f93ec1-fa24-4f57-95fb-43c25e769f03 I have spoke with a number of students over the years, and many students see home automation...
  • Blog Post: Arduino or Netduino: Adding Bluetooth using the JY-MCU HC-06 V1.XX

    Finally got it to work.  Seriously, the voltage for the JY-MCU is REALLY 3.6 to 5.0 volts.  This means that the 3.3 lower voltage provided by the Arduino/Netduio board will be flaky, and what does flaky mean?  It means that it will randomly and infrequently, at least with the board I have...
  • Blog Post: Arduino/Netduino: Transformers and connecting to the internet using Ethernet

    So what do you use the Ethernet for?  To catch an Ether Bunny… Get it, huh?  Get it?  Seriously that is my best joke ever!  Good thing I am not a stand-up comedian right? Anyway, in my wandering around the forest of technology, I am on a path to connect my Netduino to the internet...
  • Blog Post: Arduino or Netduino: Sensor and Actuator, testing the circuit w/o CPU

    When using your Arduino or Netduino to connect with the Web and then the “Cloud” you need to use the correct Write and Read requests. In this blog will use the Netduino only because it has a network connector on board, my Arduinos do not have a network connector, and there is a cost to getting...
  • Blog Post: Internet of things: Summer Reading List

    These are books you have to pay for, they are not free.  Some are older, and those will be noted.  I have read a few of these and others I haven’t but plan on checking them out.  Getting Started with Netduino (O’Reilly, make sure to check to see if there is a coupon) Getting Started with...
  • Blog Post: Internet of Things, Arduino/Netduino: Counting the closure of a switch

    Counting things and then storing them for later use in data analysis requires a bunch of things.  One of the main things is that the number of times a switch closes is an important data point for many categories of work:  manufacturing, retail, physical security and safety to name a few. It...
  • Blog Post: Arduino/Netduino: Using the RGB smt LED Keynes Sensor

    I am using the Keyes Sensor which came in a kit I bought from Amazon.com, you can get the sensor kit cheaper elsewhere (now I know).  The LED looks like the picture.  The LED has a blue, red and green LEDs on it.  The leads on my sensor appear to be incorrect, the Green and Red are reversed...
  • Blog Post: Netduino: Setting up the Netduino Plus 2 with Visual Studio 2013

    I like C#, and to get started today I just had to have a quick IM with the C# expert on the Team Jerry Nixon.  To get some luck I guess.  My goal this week is the connect my Netduino to Azure and use one of the cheapie sensors that I bought a couple of weeks ago.  You know I often do not...
