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 ...

[Craig Shultz], a mechatronics grad student at Northwestern University, sent us a video of his group’s project from last winter: a 3D bubble display. We’ve seen some pretty impressive a… ...

A US based but China manufactured LED display can interpret 3D video content at the size of 180-inch. The commercially behemoth can be further expanded in a trio arrangement to gather up to 360 ...

The LED Cube is powered by an Arduino Nano ESP32-S3, leveraging its dual-core architecture. Core 0 handles LED control via the FastLED library’s I2S driver for efficient rendering while Core 1 manages ...

However, his latest video uses some a MAX7219 to create a 600 character scrolling LED sign. You can see a video of the thing, below. Spoiler alert: not all characters are visible at once.
