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.

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 ...

P10-Matrix-Panel-Clock Arduino clock based on single color P10 Matrix Panel Clock is a device, based on Arduino microcontroller and real-time clock DS3231. It uses two LED matrix modules P10 for ...

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.
