Arduino 7-Segment Display Tutorial | Single & Multiplexed Digits
Display numbers on classic 7-segment LED displays with Arduino. This tutorial covers single-digit and multi-digit (multiplexed) 7-segment displays, wiring, segment encoding, and using a TM1637 or MAX7219 display driver for easy control.
🔢 What you'll learn and more topics to research:
• How 7-segment displays work (common anode vs cathode)
• Direct wiring to Arduino pins and segment encoding
• Multiplexing multiple digits to save pins
• Using TM1637 or MAX7219 driver modules for easy control
• Project: digital clock, counter, score display
📌 Part of the Arduino Prototyping Basics: Outputs series.
