The driver uses the way the individual diodes of the matrix are wired and allows multiple diodes to be activated simultaneously within one cycle. This ultimately means that the refresh rate can drop ...

NYC beaches are where tropical beaches addicted to meth go to die. So says [Vije Miller] in his write-up for his Arduino sand matrix printer. It’s a clever idea, five servo-operated cardboard plungers ...

This project demonstrates how to control an 8x8 LED dot matrix display using an Arduino and the LedControl library. The code initializes the matrix, displays a predefined pattern, and refreshes it ...

18 year old maker and developer Nikodem Bartnik from Poland, has created and awesome DIY Arduino-based dot-matrix printer, capable of creating art on paper 55 cm wide and as long as you need, thanks ...

We’ve seen a lot of unique large-format scrolling message boards on these pages, but most of them use some sort of established technology – LEDs, electromechanical flip-dots, and the like – in new and ...

[Credit: The Life of Kenneth] Twitter tickers have been around for a little while now, but this creative use of an old dot matrix printer by a modder named Kenneth is really a fun way to utilize old ...

8×8 LED Matrix modules are now widely available, and fortunately they are easy to use with our favorite Arduino microcontroller. 8×8 LED Matrix module have many applications in real life, such as ...

Most of us have an 8x8 LED matrix from one of our Arduino kits. What can we do with them? This module investigates how to use these interesting devices. Along the way, we describe a fun electronics ...
