Arduino code

This project is about writing, reading and modify information on SDcard. Data is a message that we obtain from GPRS. You don't need to implement any code for GPRS but this aspect can be useful for you to understand why and how to write the data to sdcard. There are 2 files: "[login to view URL]" and "[login to view URL]" - In "[login to view URL]" will be saved all sensors data durring the loop. We will have a header. A file as example will be provided. - In "[login to view URL]" we write the messages when GPRS can't send it to server. If this file exist and GPRS can transmit, will take a message from this file and retransmit it. After message was retransmited, will be deleted it from the file. If the files reache more than 1Mb, create another file using the time as name. for example: [login to view URL] (year-mont-day-hour-minutes-seconds). We need to diferentiate these files to know the provenience: data or message.
