About: Always original ideas for Arduino!

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!!

    Question 3 months ago

    Thanks for this great project. I want to know that can I use Arduino
    nano in this project instead of Arduino UNO? If answer is yes than what
    changes should be done to work this project?

    The file is there. Had you try it again?

    I am not sure about this issue.

    Liked the simple 2 matrix approach for a clock with multiple modes!

    you get my vote!
