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 ...

Fig. 2: Circuit diagram of GPS based dot-matrix display clock Note that the system works with two different Arduino boards, one of which (Board2) controls the dot-matrix display and the other (Board1) ...

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.

Simple Arduino Nano Clock with LED matrix displ. Contribute to mylms/Arduino-Matrix-Clock development by creating an account on GitHub.

This project aims to build a digital clock using a real-time clock chip (DS3231) with battery backup, a liquid crystal display (JHD 204A), and an Arduino Uno board. Let us try to design our own ...

In this tutorial we will make a Digital Clock by interfacing RTC module DS3231 with MSP430 and display the time and date on 16x2 LCD.
