The Dot Matrix Display. When we are talking about the MAX7219-based dot matrix display module, it consists of 64 LEDs connected in a row-column format so that we could easily control them with the ...

The dot matrix clock was built without the use of a regular Arduino board but uses the ATmega168 with Arduino bootloader and assembled on a breadboard. An RTC clock compensated by temperature is used ...

The LEDs on the 32x8 Dot Matrix Display will react according to the signals that Arduino receives through a microphone that is connected to its analog pin. Arduino has built-in ADC input audio signals ...

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 ...

Arduino source code, which created by this, will needs an external library "MAX7219.h" and "MAX7219.cpp". You can find it in the Arduino folder of this repository. Copy those files into Arduino ...

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 ...

The frame for the Arduino dot-matrix printer was created using the fantastic Autodesk Fusion 360 application which is free to download and install.

A while back, [DragonMinded] picked up a bunch of old arcade and pinball parts from a guy on Craigslist. These parts sat around for a while until a really neat plasma dot matrix display was found i… ...

Today, I'm thrilled to guide you through the steps to create your very own 32x8 compact LED matrix, driven by an Arduino Nano. For a double fun, the used LEDs are purple. Let's dive right ...

Messages are composed on an old PS/2 keyboard through an Arduino and a 16×2 LCD display, and punched onto the tape a dot at a time. The punch is a large darning needle riding on the remains of an ...
