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 to the Spark Cloud.  Then you…

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). If…

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…

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 make money off this skill.  It…

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 built software, when the LED lights up you should see this in the Visual Micro…

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…

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 you are not familiar with the General Theory of…

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…

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 be that…
