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 ...

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 ...

And we end up seeing all kinds of display techniques being used to show time. For the simplest of builds, 7-segment ... an Arduino Nano clone, a DS3231 RTC, a Lithium battery, and some buttons ...

The 7-segment display certainly is a popular build ... Cutting, stripping, and soldering 186 wires took him almost 10 hours. An Arduino Uno serves as the brains of the device and there is a ...
