IMG_20181023_185808.jpg Hello !Welcome to Abid Cg creator blog . Here is a short tutorial on How To Make An Led Matrix Clock.Basically it uses the Real Time Clock Module Ds3231 and prints time in led display. I am not the creator of the whole code.All credit goes to Petan His GitHub link is Here . If you tend to make this awesome clock,let's get started now. Parts needed:
  1. Arduino UNO or Nano
  2. 4 Max7219 matrix display.
  3. RTC ds3231
  4. Two Buttons
  5. Soldering Tools
Circuit diagram: diag courtesy www.mylms.cz

 Important Notes : Please download the LedControl library from this link
 Hold Two Buttons together for time setting. Use one button for increment and another to Set. Use a good power supply. Here is some pictures of my clock.

      Hi!
      There is no such "hr" function in the code. You may have accidentally changed the code. So, download it again and compile it.

    I was able to build this project using the info you provided. Thanks! Buttons and display work great. Looking at the code, the Serial input is used also to set the rtc components. Question: Are you able to provide details on the Serial input logic and use? I guessed that E22 would change the time to minutes=22. But that is not the what occurred. Thanks again!

      I was too hasty...I followed your blog and found that the clock code I used is NOT the latest version - I found v5 and I may have installed v1 or 2. I will test v5 out. Thanks!!
