Hi Don,

Yes, referring to the picture in the other post, the white grid on the right hand side is the bread board.

All the ground slots on the Netduino are connected together, so it does not matter which one (or ones) you use.

I'm not sure where you are based, but in the UK I can recomend a company called Hobbytronics for electronic supplies. (I have spent much too much there!) From them you might buy a breadboard like this one. They have several sizes, and there are lots of other suppliers too.

And if you have an unlimited budget, you will not regret getting some jumper wires too.

Hope this helps - Paul

Edit : If my reply seems a bit odd, its because I started typing this before CW2 replied!

Hi Paul - Thanks for the information. I have been looking at Sparkfun and Adafruit and I will check to see if perhaps they have the one you mention. I live in the US but would think I could get the same thing. Also, thanks much for the suggestion of the wiki. I will be looking through the tutorials to try and get a better understanding of how to wire.

Thanks!

Don

Not sure if this will help, but I ended up using a TiVo wireless N adapter that I already had and it works great. It has a cat5 cable and RJ-45 connector that plugs right into the ethernet port on the Netduino Plus. The other thing I like about it is the WPS capability for security with the router. I had it up and going in just a few minutes.

They can be found pretty cheap on eBay.

The other thing I like is that it shows the Netduino's MAC address in my router's client list and the IP address gets assigned to the Netduino. Since I am new to Netduino I don't know if there are ever problems otherwise but was happy to see that the wireless adapter just acts as an extension.

Other quick note is I am using a Belkin router but I would think could use other routers (it has the ability to enter encryption key if you don't have WPS on your router), and the adapter needs a power source.

I hope this helps.

The pull-up resistor should be 4.7 kΩ (you are missing the kilo- prefix in your post, which means 4.7 Ω, but I assume it's just a typo). Connecting the sensor to Netduino directly is not really possible, because the leads do not reach the necessary pins (input pins are too far from the power), you'd need to solder some wires to the sensor leads. You can see sample connection for example in this post.

Thanks for the replies gentlemen. Yes, I did mean to have the Ω symbol but did not know how to make it. I did not however, know that it should be kΩ which I see makes a big difference. In looking at the pack of resistors I have I can see that they are 2 different things so thanks much for that. The tech I conversed with did not denote that and probably thought my experience level was such that I would know.

Thanks CW2 for the link to the post and picture. I have a couple of questions for you:

1. I mostly get the concept of the photo but I am not certain what I am looking at. Is that what is considered a breadboard? I recognize it from some documentation and tutorials I have read through. If so, can you recommened what I need to purchase?

2. Does it matter which of the 'Gnd' slots the Ground wire is connected to?

Thanks again much for your help. It is greatly appreciated.

Hi All - Sorry for the elementary questions on electronics. I am a .NET Developer who is just getting started using micro-controllers, specifically the Netduino Plus. I have been running through many examples, learning basics with the .NETMF, learning to flash upgrded software etc. I have literally no experience with wiring and such except for the wire I put in the 3.3v hookup and touched the gold erase pad. That's it.

Now that you know my electronics level, on to the questions...

I want to use the DS18B20 Temperature Sensor that I bought from Sparkfun. The technician gave me a little verbal layout of the wiring:


Sensor-------->Netduino Plus
-GND(black wire)----GND
-VDD(red wire) ----3.3V
-DQ(white wire)---Digital Pin on the Netduino

She also mentioned putting a 4.7 pull up resistor between the signal and power pin. I actually sort of follow what she is saying after reading a couple of things online and some information from a Netduino book. I feel like I need another piece like a breadboard (no idea which one to get) and some jumper wires. I purchased a pack of resisitors and so I am good there. It appears that wiring this thing directly to the Netduino Plus is either impractical, ill-advised or both. I have seen a few postings on this subject with pictures posted on how someone has wired it up although I am not certain what I am looking at.

Any direction on that is appreciated. I did run through a breadboard tutorial to which another user posted a link but I was wary because the tutorial was hard to understand and the comments seemed to dispute the authors calculation of resitance provided by X number of resistors. The last thing I want to do is burn up some hardware (obviously).

Additonally, I have questions about OneWire support. I have read through several posts trying to figure out where that support effort currently is for the Netduino. I have thus far noted the following:

1. A gentleman named CW2 has produced a very nice implementation of OneWire support. There was talk of including it in the official release but that did not come to fruition.

2. The Microsoft .NETMF 4.2 has OneWire support in the Microsoft.SPOT.Hardware.OneWire assembly.

3. At this point in time, if I want to use the DS18B20 Temperature Sensor I need one wire support and will need to flash the modified (unsupported?) version created as a special build and includes CW2's implementation. My understanding is that the Secret Labs SDK would need to include a Netduino Plus specific implementation for whichever (CW2 or Microsoft.SPOT.Hardware.OneWire) to use this device.

If I have misstated anything above please do correct me. All of this is my next big step in understanding the basics of how to get this sensor to work properly for my project.

I thank you very much for taking your time to read this and certainly with any help you can provide.

Regards,

Don

Hi Thomas - Thanks for posting this. I have the DS18B20 One Wire temperature Sensor (https://www.sparkfun.../products/11050) and was wondering if this would work the same for what I have? I am a .NET Developer who is a complete newbie to electornics. Is there a chance you could post how you wired up your temperature sensor to the Netduino Plus if it is not too much trouble. I have the NP 1 but would assume there is not much of a difference? Thanks! Don
