1  Topics / Home Automation and Networked Objects / Re: Control Arduino via SMS without SHIELD GSM on: August 11, 2012, 04:40:01 pm
you would probably need some sort of communications interface. If you have a land line you can setup an SMS gateway on a computer. Have the computer parse the SMS message and send it to the arduino via serial. Alternatively, you could use an Ethernet shield, and either have the original computer parse the SMS message from the gateway and send it via Ethernet to the arduino. Or if you are feeling up to it you could write your own sms gateway interpreter that runs solely on the arduino that has wi-fi, ethernet capability.

There are some free implementations of SMS gateways available on linux. I'm not to sure about windoze.
2  Using Arduino / Sensors / Re: GPS receiver choices on: August 11, 2012, 03:36:07 pm
I have used the sparkfun module (LS30001) it is very accurate. Down to about 6". There is a library called TinyGPS. that will get and parse the values into an object so you can use them within your sketch. I have an example sketch that uses this library to find the distance between two points on earth using the harversine formula.

can be found here: http://apexlogic.net/code-bank/arduino/serial-gps-find-distance-between-two-points/

it has links to the TinyGPS as well as the actual module datasheet. Enjoy.

You can use a python script to listen to the serial port and save the data into a text document. Excel can import files in .csv and .txt (with tab as a field separator). you can view more information on excel importing at http://office.microsoft.com/en-us/excel-help/import-or-export-text-txt-or-csv-files-HP010099725.aspx

here is a an example to read information from the arduino through a python script.
4  Using Arduino / General Electronics / Re: best way to get components from pcb on: August 11, 2012, 03:21:32 pm
If you don't need to save the actual PCB and just want the components I usually use a heat gun onto the backside of the board. Once it gets molten you just smash the corner of the board onto something and the components fall right out. Then you can clean them up with solder wick if they fly off with some solder on them.
5  Using Arduino / Networking, Protocols, and Devices / Re: Arduino doesn't take serial gps data when mounted on bread bord on: July 17, 2012, 09:25:40 pm
What you want is pins 2 and 3 from the atmega328 which are digital 0 (RX) and digital 1 (TX) within the arduino pinout. That is if you are using hardware serial.
