The TM1637 4 digit 7 segment display module solves the problem of using many pins for serial communication by reducing the number of pins needed to control the four displays using only four pins instead of twelve that are used by many of the 4 digit displays.

In this tutorial I demonstrate how the TM1637 display is interfaced with Arduino in a number of simple applications including;
2:10 Up-down Counter
3:15 Temperature Display from LM35 temperature sensor.
4:00 Time display from DS3231RTC
