ESP32 TM1637 4-Digit 7-Segment Display

We are controlling a 4-digit 7-segment display module with a TM1637 driver using an ESP32. Using just 2 GPIO pins (CLK and DIO), we run a counter from 0 to 9999, adjust the brightness level, and display the colon (`:`) character in clock format. Thanks to the TM1637Display library, controlling numbers, hex values, segments, and strings is very easy.
