Explanation

Project uses raspberry pi and gps module to get current car speed and live speed limit for road and provides indication if speed limit is crossed.

  1. Current speed is received from GPS module.
  2. Current coordintes are received in HHMMMMMM format from GPS module and converted to degrees
  3. Current speed limit of the road is received from Here Maps API using the degree coordinates
  4. Speed limit in mph is normalized to base of 5 and compared with current car speed to control LEDs based on status
  5. Status available - within speed limit, nearing speed limit, above speed limit, above speed limit+5
