/*
	Clock example example (Extended class example)
  Display a clock on the display. For this demo you can add a speed multiplier to make the clock run faster. For a real clock you want to use a delay of 1 min or even use a Real Time Clock module (RTC)
	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
