この投稿ではArduinoを使って7セグメントLED(516AS)を制御しようと思います。 目標は点灯箇所を2進数で制御し、7セグメントのLEDを0から9のパターンで点灯させることです。 初めての投稿で、至らない点多いと思いますが、質問等をコメントしていただければ ...

This project simulates a traffic light system using red, yellow, and green LEDs. A one-digit 7-segment display counts seconds for each traffic light phase, demonstrating sequencing and timing in ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

For those of us who remember LED calculators, the HP 5082-7400 series red “bubble” displays hold a special charm. Available in 3, 4, or 5-digit varieties, these multiplexed 7-segment displays provided ...

These days they’ve been replaced with character LCD displays or even brightly colored graphical displays, but if you’re trying to display data on one of your projects, there’s nothing like the classic ...
