This TM1650-based 4-Digit 7-Segment Display Module integrates a 0.36” 3641AS common cathode display with three onboard push buttons, creating a compact and practical mini user interface solution.

The module communicates using a 2-wire interface (DATA, CLOCK), allowing both display control and button reading using only two microcontroller pins. It is ideal for counters, timers, menu systems, and embedded UI applications.

/*

written by Technical team @ UGE-ONE.COM
Modified to use built-in buttons for count up, down, and reset

  Button mappings:

  - Button 1: Bit 27 (count up)

  - Button 2: Bit 15 (count down)

  - Button 3: Bit 19 (reset)
