/*
Printing numbers example
Demonstrate a couple different ways nubers can be printed: positive, negative,
with padding and with rollover.
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
