project guidance for accident tracking system using MEMS acelerometer

Using Arduino Project Guidance
1

Hi,
I'm working on accident tracking system,that detects the fall and tracks the location and sends an information to the mobile.I have a very less idea about the interfacing part of Arduino with ADXL345,GPS and GSM.I wanted a good guidance in the software part as well.Is it necessary to connect the external pull up resistors while interfacing ADXL345 with arduino?Please reply me as soon as possible

Is it necessary to connect the external pull up resistors while interfacing ADXL345 with arduino?

Yes.

Google "interfacing ADXL345 with arduino" and follow the first few links. You are hardly the first person to try this.

Hi. Um.. what kind of accident??

Both Humans and Nature have almost infinite variety in this...
