Very cool. As a newbie, I am trying to read http://search.murata...mmended_Circuit to understand what resistors to wire-up inline with that buzzer (still not fully grokking schematics). Is there a "Fritzing style breadboard view" that shows how to wire up that Piezo part?

 

Thanks.

Can anyone recommend a piezo buzzer/speaker part from any supplier (Adafruit, Sparkfun, Amazon, etc) that works well with the Netduino Plus 2?

 

Thanks.

Hs anyone discovered anything new bout this product with the Netduino?

What are experienced folks doing to read configuration information from files?

I did not see a way to use the System.Configuration bits, and I would like to set a destination address for sending output via a file to avoid hardcoding.

 

All ideas appreciated.

 

 

Thanks.

 

 

(.NET MF2, NetDuino Plus 2, Visual Studio 2012)

Grant, that does help a bit.... In the non-Micro .NET Framework, the System.Configuration.ConfigurationManager class wraps a well-defined XML structure for containing strongly typed key/value pairs of data, and other meta-info. If you have written something yourself then there is probably no baked-in equivalent to ConfigurationManager, so I will write something myself, as you have already done.

 

 

Thanks.

I have gotten a lot of mileage out of .NET using Mocks for unit and integration tests in Visual Studio.

 

Is there an equivalent for the Micro Framework?

 

My eventual goal is to read from 4 sensors and do something with the captured information. Before I get to that goal, I was thinking that I could exercise the other parts of the system by creating "fake inputs", injecting known data into their structures/wrappers, and then debugging with that fake stuff.

 

Is that possible?

 

 

Thanks.

 

Hey all. I am trying to find a source for an HD47780 LCD display that will do 20x4 that does not require soldering.

I saw this blog post:

http://10rem.net/blo...th-the-netduino

as well as the codeplex library, but cannot seem to find anything on the "usual" online retail places that have the part I can wire up to a breadboard, and then a Netduino //+, without soldering anything.

All ideas appreciated.

Thanks.

It did... I actually web-searched a bit, read through his stuff, and that is how I landed here and discovered the Netduino platform.   And it was a happy discovery!

 

I plan to attempt something a little different than what Jarrod created.

 

I was thinking of a configuration where space for each sensor is cut into the track, and as a car rolls over them, time is captured (via IR or pressure or sound or something (I need at minimum thousandths of a second precision, prefer ten-thousandths). I am trying to remove the need to have a paired sensor, remove the need to have hardware above/below the finish line. Just something that points "up" and can tell when something is over it.

 

I saw the below sensors via web searches but am not sure if Netduino driver support exists for 4 simultaneous sensors, and if they would actually "work" for that purpose and can be powered by the Netduino itself.

or

or

https://www.sparkfun.com/products/9375

or ?

The time captured would be displayed on a simple web page and also on a 4-line LCD (reason why I'm leaning towards a Netduino Plus 2).

 

I am also trying to think through how to start the timing (open/close start gate?). The sky is the limit there.

 

I have several months to get this done, so all thoughts appreciated on how to get started properly.

Hey all. I have developed on .NET for years and years (I can recall combining 1.0 and 1.1 assemblies for system deployments and am still in therapy over that). However, I just discovered the MF and Netduino platform is week, and am really excited to try it out for a real world project. I am starting form zero knowledge , but have about 5-6 months to get the project completed. My plan is to capture and display the event timing of wooden model race cars assembled by kids, each car rolls down a "slot" and the one withi the best aerodynamics and gravitational treatment wins. I currently have a flaky electronic race timing system in place, which needs to be replaced. My current idea is to have a weight-sensitive sensor at the starting line in each slot, and have another at the bottom. On a push button signal, I would detect when the weight was released from the start line sensors, detect when each weight was applied to the bottom line sensor, and then diff and display the elapsed TimeSpan. Other than knowing I want a Netduino2+ (so I can eventually post the results over a protocol to a laptop, or show on a web page), and knowing I need to read some books, I don't know what hardware to acquire or direction to take. All ideas appreciated and excuse any obvious ignorance. Thanks!

Paul (and Hanzibal), you have given me a lot to think about. I am going to acquire some hardware now, start with the basics, and come back to this topic. Thanks!

Thanks for the thoughts and responses.

 

The cars have weight restrictions, so putting things like magnets on them is off-limits. I think that takes me back to the idea of having some kind of sensor facing "up" and detecting when a car passes over them by casting a shadow. The raceway has fluorescent lights, so I think something like embedding a mini photocell (https://www.sparkfun.com/products/9088) might be a good move; but I wonder how long the wiring can be between the cell and the Netduino, what/where resistors need to be, and also if I can read 4 at a time with a Netduino Plus 2.

 

What do you think of using the light-detection strategy and that particular part, which was mentioned on http://johnnycode.co...h-the-netduino/ ?

 

Thanks again.

[EDIT]

The title should be "Large LED for Scrolling Tweets" but iOS autocorrect bit me again. And I don't seem to be able to edit the title or delete bad posts.

[EDIT]

 

 

I am probably getting ahead of myself since I am only past the 2nd blinky experiment, but I was wondering where I might be able to find a ready-to-plug (no soldering required) serial LED display that would emulate this on a Netduino+2: https://sites.google...tmatrixdisplay/ My general web searches have not turned up anything decent, and Sparkfun and Adafruit don't seem to have anything available. All ideas appreciated, thanks!

Hi all. I only recently discovered the Netduino platform 3 days ago, and am very happy that I did! Please excuse any part of this post that reeks of ignorance. I am trying to come up with a "different" way of timing a pinewood car race. For those not intimately familiar with it, a set of hand-carved wood cars roll down a track, and the one that gravity and aerodynamics treats the best wins. In contrast to the awesome++ work done my Jarrod Sinclair, I am interested in doing something like this (there are 4 lanes on the track): 4 sensors at the top of the track, each registering datetime when a car rolled over them, saving it at "start time" for lanes 1/2/3/4. 4 sensors at the bottom of the track, each registering the datetime when car rolls over the track, saving "finish time". The Netduino Plus 2 would be set at the bottom of the track with a monitor to display the TimeSpan difference for each lane. So...... Do (flat low profile?) sensors exist that register simple touch impact? Can 8 be wired to a Netduino 2 (plus?)? Is this a crazy idea? I am just now reading over some "getting started" text to get familiar with the platform. I appreciate ideas and input on this. Thanks!

Can anyone recommend a TTS shield/part/etc and driver that would work with a Netduino Plus 2?

Thanks.
