This project is about a Digital and Binary Clock using Arduino and two LED matrix with MAX72XX and RTC (Real Time Clock) including several features.

Features:
Digital Clock
Binary Clock
Mode AM/PM
Mode 24 hours (international mode)
Time & Date (Day, Month & Weekday)
02 different types of fonts (conventional & stylish)
RTC keeps the time and date when the clock is off
The internal memory of RTC can record the operational modes
Two digits sharing same LED display
The operation is very simple using the Arduino’s restart button.

Every time you turn on or restart the Arduino, a new clock mode is set automatically.

To make this project so simple, I dedicated a lot of creativity and ingenuity to the code to add various features.

I hope you enjoy it!!”
