The examples are broken up into various sub directories for each i/o class

• ioUsingArduino
  Contains example sketches that are for LCDs that are wired up directly to Arduino pins.

• iofrom8574
  Contains example sketches that are for LCDs connected to a backpack using the i2c PCF8574 i/o expander chip to control the LCD.
