By using these driver ICs, the complexity of wiring and control is significantly reduced. “I’ve built a digital clock made out of 144 seven-segment displays controlled by an Arduino Nano.

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 ...

Inside the boxy blue base is an Arduino Nano, a DS3231 real-time clock module, and a perfboard full of transistors for switching the LED strips inside the segments.

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 ...

The case is made from 4 mm laser-cut MDF with wood-grain foil on the outside. Inside, there’s an ESP32 to run the show, along with an RTC module and three four-digit seven-segment LED displays.

A small STN LCD module is now available to complement the fully programmable IS series Smartswitch. The LCD's wide, high-contrast viewing area measures 13.9 by 10.6 mm. To maximize ...
