5Pcs 0.56 Inch Green LED Display Tube 4-Digit 7-segments Module

Example1

/*

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 pin D4* connect TM1637 pin DIO to pin D5* connect TM1637 pin Vcc to pin 5V* connect TM1637 pin GND to pin GND
