 #### Parse NMEA GPS Sentences
 
-Previously we shown how to show the GPS data on the Serial Monitor, but it was not possible to evaluate those messages (NMEA sentences).
-To do so you can use an **NMEA parser** that will convert the messages received from the GPS modem and it will parse and save them into variables, you can use the **107-Arduino-NMEA-Parser** library.
