As far as my car, I do keep it locked, but I think it sucks that people are stealing things. No ethernet port--I'd use a shield.
2  Using Arduino / Project Guidance / Catch a thief on: June 10, 2013, 11:40:57 am
We've had a string of car robberies in our neighborhood over the past week. The burglars are basically going around and looking for cars that are unlocked and taking things. I'm thinking this might be a great opportunity for a project. One thought I have is to put some kind of sensor on the door, then when it is opened trigger my camera to take a picture (my camera would be inside, so I'd have a second Arduino or remove shutter release to get a signal, not sure yet).

Another thought is to use the distance sensor/ethernet shield to alert me on my computer the moment the door is open.

Anyway, I'm looking for good suggestions and ideas.
3  Using Arduino / Installation & Troubleshooting / SMD/surface mount with a breadboard on: March 28, 2013, 07:49:23 pm
Not sure if this is the right forum, but advice is appreciated. I want to try to use a suface mount demultiplexer with a breadboard. Is there some sort of solderless adapter than can be used? I've searched and really haven't found anything like what I'm imagining (hoping) to find.

Thanks...

Yes--my goal wasn't to do anything fascinating--just to show how a demultiplexer works.

I just discovered something--if I am too close to the sensor (3 feet), I get inconsistent results. 5 or so feet and I get consistent results. Odd.

@afremont --Its a samsung remote for my Time Warner DVR box. When I output raw codes I can see them just fine. After some digging it does appear that the samsung remote is using 38kHz carrier frequency, which would be compatible with the IR receiver I am using-- https://www.sparkfun.com/products/10266

Supposedly Samsung remotes use 38kHz. When I use the IR library I have to output raw codes to see them with my Samsung remote. It works--I see codes--but they are different every time. Any suggestions?

Did you ever get a solution here? I'm trying the exact same thing--And seeing, as you did, different values each time.

Might a voltage regulator on the power source help?
12  Using Arduino / Sensors / Re: TMP36 - Temperature Sensor drops over time on: February 28, 2013, 03:35:19 pm
The wires are 3 inches or so.
13  Using Arduino / Sensors / TMP36 - Temperature Sensor drops over time on: February 23, 2013, 01:37:09 pm
I made a simple temperature readout using this:https://www.sparkfun.com/products/10988

I set it up so I could see a readout on my LCD of the current temp, highest recorded and lowest recorded. It starts off just fine, reading room temp right around 71 degrees, but over time the temperature readout trends lower and lower, eventually going down as low as 64/65 (Fahrenheit). If I restart the temperature starts out again and a more expected range. What are some reasons why this dropoff might occur?
14  Using Arduino / Installation & Troubleshooting / Re: Arduino Nano quit working on: February 17, 2013, 08:49:32 pm
Not sure what I would have done to short it out. What are some things that would inadvertently cause that?
15  Using Arduino / Installation & Troubleshooting / Arduino Nano quit working on: February 17, 2013, 05:28:25 pm
My arduino nano suddenly quick working--No longer detect as a USB device and the power light seems faint (at least not as bright as it used to be). Pressing the reset button makes the power button flash, but nothing more. Any advice?
