/*
	Fun Print all example

  This is a demonstration off a lot of the possibilities of the Fun superclass

	The circuit:
  * connect TM1637 pin CLK to Arduino pin D4
  * connect TM1637 pin DIO to Arduino pin D5
  * connect TM1637 pin Vcc to Arduino pin 5V
  * connect TM1637 pin GND to Arduino pin GND
