Hi, I want to design a GPS car tracker with SIM808. Right now I can get GPS data including latitude, longitude, speed, and ... from SIM808. I want to be able to get the legal speed limit for the latitude and longitude of the place using a microcontroller. How can I do this?

    Top Tips:

    1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
    2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
    3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
