An LED-matrix clock made with Arduino, using a DS3231 RTC module and four MAX7219 LED-matrix controllers. It also has an ambient light sensor for controlling the brightness.

An image of a dot matrix display is shown below. MAX7219 Chip 8-Digit LED Display Driver The MAX7219 chip is a serial input/output common-cathode display drivers IC that can interface microprocessor ...

Arduino LED Matrix Clock This is a simple Desk Clock made from five 8x8 LED matrices and an Arduino Nano / Pro Mini This clock uses a DS3231 RTC IC, which is not only quite accurate, but does also ...

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 ...

Presented here is an LED-based 2D GPS Based Dot-Matrix Display Clock. This project is for making a GPS based LED dot-matrix clock.

Arduino Display Matrix (32 X 8 DOTS) 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 ...
