Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

This project demonstrates an Arduino-based counter using a 4-digit 7 segment display. The counter counts from 0 to 9999 and displays the current value on the 7 segment display.

Arduino and TM1637 4-Digit 7-Segment Display Circuit Diagram Now that we have completely understood how a TM1637 seven-segment display driver IC works, we can connect all the required wires to Arduino ...
