ThingSpeak

I received a Netduino Plus from CanaKit on Monday and got cracking on writing a client application for ThingSpeak web services. The process took a solid day, but I really found the Netduino Forums helpful in getting started with this emerging platform.

Attached is the ThingSpeak Solution / ThingSpeakClient Project for Visual Studio. To get started, all you have to do is download, unzip, and open the "ThingSpeak.sln" file.  ThingSpeak.zip   82.55KB   125 downloads

For my project, I connected the output of a photo resistor to an analog pin on the Netduino Plus. I read the value every 30 seconds and update a ThingSpeak Channel. I also check the value to see if it's "high" or not. If it's high (above 500), I update my channel status with, "Someone is in your room!!!"



ThingSpeak is an API to allow for sensor data logging, message brokering, location tracking, and connecting devices together. We are under Beta, but we will release soon - next week is my hope. The API will also be on GitGub so you can run the web service locally. If anyone would like to try it, just send me a message.

I have posted a full tutorial on how I completed the project. Most of you are going to have a good sense already on how to connect the Netduino to the PC, setup the SDK, configure the network settings, but I wanted to document the process and have a record for what I learned. Maybe it will save someone some time when they are first getting started.

Here is the tutorial on the ThingSpeak Community site for getting started with the Netduino Plus, sending HTTP POSTs to web service, and using the ThingSpeak API.

If anyone gets to test this code, let me know. I am interested in seeing what you come up with and the results that you see.
