ATtiny85 and i2c LCD backpack plus rotary encoder
/*
Demonstration sketch for Adafruit LCD backpack
using MCP23008 I2C expander
Uses the ATTiny 85 (replaces Trinket below)
Also hooked up a rotary encoder with a button.
The circuit:
* 5V to Arduino 5V pin
* GND to Arduino GND pin
* Display i2c backpack CLK to Trinket GPIO #2 (Arduino pin 2/attiny85 pin 7)
