+  Arduino TFT text example
+  
+  This example demonstrates how to draw text on the 
+  TFT with an Arduino. The Arduino reads the value 
+  of an analog sensor attached to pin A0, and writes 
+  the value to the LCD screen, updating every
+  quarter second.
+  
+  This example code is in the public domain
