FYP SEM 2 (WEEK 2 & 3)

week 2 & 3 schedule

- do the configuration of GPS
- using the command that got from internet
- command for GPS (to read latitude and longitude of pointed point)
-study and make research about Arduino

Purpose:
- to create GPS data that can read the latitude and longitude of the pointed location
- to expose about the command that can be used in the Arduino
- study and try to find a solution why the program have many errors.


the sample of configuration
