I saw this and thought it might be a "simple" project for a beginner like my self: http://www.dougsword...om/gallery.html Since it's mainly turning a set of LED's on/off. The hardest part I think will be designing it to look good. I haven't used my netduino in a while and want to start again, but I've never used the digital ports, only the analog. I've read the forums a little and haven't found any answers to my main question, which seems like it shouldn't be too hard: How can I turn LEDs on/off with the digital ports? I believe I can do this without the complexity of a shift register/etc because I can tie one word to one port: ten half quarter twenty five minutes past to one two three four five six seven eight nine ten eleven twelve is 20 words, "it is" and "o'clock" will always be on. I'd like to set up a simple mock up with 2 or 3 single leds and turning them on/off through the digital pins and once I know for sure how to do it i'll plan on making the enclosure and LED grid. Any advice would be great, Thanks in advance!

After a couple hours I finally got a good reading from my photocell, so I moved on to the temperature sensor. Never thought it would be this difficult! I'm trying to get a temperature reading from an LM335A sensor (http://www.sparkfun.com/products/9438). One of the problems is that it requires 5 V, but I don't think thats a problem because it OUTPUTS 10mA/Kelvin, so as long as it doesn't get about 140 degrees, it wont go over 3.3V. Is there a problem with this? thread. http://forums.netdui...ch__1#entry3556 On to the real problem...reading the value in, it seems to fluctuate a lot. Similar to this These are 1 second samples: 916 912 940 939 927 928 924 936 911 920 933 936 934 936 937 I'm not exactly sure how to "describe" circuits yet, but here is my try of what I have: Ground -> Left pin Center pin -> A0, 1k resistor ->5V I'm powering via USB on a netduino plus. I currently dont have any other way to power it. Any suggests, or am I not providing enough information? Thanks for the help.

I received my netduino plus today and couldn't wait to break it open and mess around with it. I've never done anything with this stuff before, but I have full desktop .Net development experience - which lead me down this path to the micro framework. My first thought opening the box: WOW this this is TINY. There is a ton of things packed onto the board. I've seen tons of pictures and it makes sense that it would be small but it's impressive. The quality is top notch, everything looks very well done and of high quality. I did receive a micro USB cable, thankfully - because I do not have one otherwise. I still don't understand what the multi color barcode paper is for. I had previously installs VS and the SDK, so I plugged it in, walked through the blinking light demo. I called my girlfriend in explaining in excitement what I had just done and she gave me the blank "really?" stare -haha. Here I am 2 hours later I've done button press, event handler, gotten the time from the internet and blinked the LED to output it, and downloaded one of the webserver examples (But I don't have an SD card..yet). I'm addicted. This is a really great item. So, if anyone has any suggestions for things I can do with just the board I'm up for it. I've ordered a few sensors but they wont be here for a week or so. My first project I think might be to get this http://shop.modernde...cts/wind-sensor so that I can monitor when my heater/air conditioner turns on and off easily, log it to the SD card and make some charts from it. From there it will be something simliar to http://gardenbot.org/. Is there any posts or suggestions on making the netduino run off perhaps AA or a 9V battery? Thanks all for the advice I am glad to be a part of this community and am looking forward to helping where I can and learning from everyone else.
