4-Digit Seven Segment TM1637 Display interfacing with arduino

Hello Arduino Lovers,

In this post, I am going to interface 4-digit seven segment display with arduino. It's TM1637 based display and it just requires 4-pins. And it's better than conventional 4-digid SSD since that requires 12 (8+4) output pins. So, it saves our pin. As MCU have limited I/Os it's very useful.

The pins are as follows:

CLK, DIO, VCC and GND. 

It's 2-wire serial communication and it's different from I2C communication.
