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 ...

Sometimes you need to display a number nice and large, making it easily readable at a good distance. [Lewis] has just the thing for that: a big expandable 7-segment display. The build is modular, a… ...

Arduino 7-Segment Display Counter This project demonstrates how to drive a 7-segment display using an Arduino. The display counts from 0 to 9, with each digit displayed for one second. Each segment (A ...

And we end up seeing all kinds of display techniques being used to show time. For the simplest of builds, 7-segment display modules usually get dug up from the parts bin.

Working LED Control: The LED connected to pin 9 blinks on and off every second. This demonstrates basic digital output control using the Arduino. 7-Segment Display Control: The 7-segment display shows ...

7-Segment Display: $13 Arduino Protoshield: $10 (To easily mount the display on top of the Arduino. This is optional, you can just use perfboard instead.) ...
