GPS Module: Displaying GPS Data with Mini-OLED

The Code:

The code is very similar to our last guide: Programming Arduino with GPS except this time we send the returned data to the mini-OLED display instead.

You may need to install any missing libraries, to learn how to do this you can follow our guide here: How to Install Arduino Libraries
