In about 3 weeks, I'm doing a presentation on NETMF and Netduino to the Alaska .NET Users Group.

I was planning to touch on

• The history of NETMF (SPOT)
• Limitations
• Fun things you can do

as well as demos

• The standard blinking LED
• Reading serial data from a RFID reader
• Displaying data on a LCD
• Reading analog values

and vendors

• Secret Labs, LLC
• GHI
• Device Solutions

And Arduino shield compatibility. Does anyone have suggestions for things I should cover or a neat demo I could do?

I was also planning to mention a few of the projects people on this board

• Chris's QuadCoptor
• Fabien's Water Heater Energy Saver
• etc

Thank you for your input!

Perhaps a sample in PWM, SPI and I2C? Perhaps even SingleWire? Just to show how to use those features.

I did a presentation about... 6 months ago I think.

I covered most of what you talked about... and I also had a 7-segment LED that I hooked up to a trim-pot to show variable speed.

Most folks (at our local user group - BAND"Bangor Area .NET Developers") were interested in:

1) shields
2) that "tool chain" is free (visual studio, etc)
3) the fact that it's C#, and means no big learning curve.
4) The ability to connect Netduino's together via ethernet (or other communication channels)

(and congrats on the presentation, from a former Alaskan)

Eric,
Thank you for your input. I had completely forgotten to mention specifics of the tool chain!

What part of Alaska are you from? I live in Chugiak (a suburb of Anchorage).

Hi Dan,

I lived in Anchorage for about a year... then Wasilla for 6. My father was stationed at Elmendorf.

And yes... the tool chain is nice... free software (that works) is always good.

Stefan, just noticed your comment. Yeah, I plan on doing PWM with an LED (I don't have any servo's avail to show talking PWM to a servo), and SPI with a '595 to show how you can get more outputs.

Unplug the pc speaker from your PC and connect it to your netduino. way more fun then a led

I didn't think of that, thanks Stefan!

Anyone up for sharing presentations when they are done? I'm doing a session at the St. Louis Day of .NET in August, an Introduction to Netduino.

Chris, when I get my slide deck done, I'll post it up, along with my notes and schematics for the demos I'm going to do. Look for it in the next week or two.

Hey Dan,

Regarding your PWM demo: feel free to use this sample which plays RTTL ring tones. http://netduinohelpe...Test/Program.cs

There are many other samples that you could leverage for other areas. If you have an 8x8 LED matrix, you could use your 74HC595 shift-register to drive with using persistence of vision: http://netduinohelpe...oWorld/Tests.cs

This sample also uses analog joysticks to demo analog inputs.

I hope this helps.

Cheers,
-Fabien.

Fabien, thank you for the link to the RTTL stuff. I will add that to the demo list!
