Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

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 ...

While 7-segment displays are all well and good, they’re considered a bit old hat these days. This project from [Matt Deeds] brings them screaming into the future, though, sporting every color ...

Reddit user Krukerfluk has created an awesome DIY digital clock using 144 x seven segment ... display powered by an Arduino Nano. The small Arduino development board has been combined with an RTC ...

things: addressable seven-segment LED displays ... And as a nice touch, individual displays can be ganged together with connectors on the back of each module. [Sean] has some code to support ...
