+# Projects
+Here are bigger files - projects. They usually combine more than one feature to produce something with some form of a use. It will be harder to preen specific example out of these, but they should run and work and produce the result expected.
+
+## m5-gps
+- Requires `tinygpsplus` library
+- GPS module (m5 v1.1) must be connected to the left port on the terminal itself. It will not work in the right side, and it hasn't been tested in other ports on the battery pack.
+- Currently displays current co-ordinates on the screen, using a black rectangle around the text area when refreshing so that other parts of the screen can be used without needing to black out the entire thing. 
+### Todo
+- WiFi lookup the coordinates with openweathermap's reverse API 
+- Button refresh instead of constantly updating itself? Is this better or worse haha
