TUTORIAL ON REAL TIME CLOCK USING DS3231, MAX7219 LED 8X32 DOT MATRIX & ARDUINO NANO 

I have seen a lot of videos and tried a lot to make one however my every attempt was unsuccessful so I gave up thinking it was a waste of time, but today I happened to see your video and it triggered me to check my long-forgotten Dot matrix Led and Arduino and I re-assembled at the very first try it succeeded. Now I feel relaxed. Thanks for the video and hoping for more related videos.

Super and very simple project. Clock is working properly most important thing that code uploaded in nano with a glitch.thanks.

I am one of the subscribers for 3 years mate .... 🤝

Great video Bro. Really helpful and informative to duty works

Code is working properly, thanks dear But need for an updation if included in code for display for Day, Date and year

Sir i saw many videos of arduino clock on youtube and used the code but there were many errors in them the code you have given is working without any error and the font is also stylish. Please make another video which includes scrolling time along with date and year with thanks

Great Job you made ... But in order to follow your example we need to Upload some Libraries in Arduino IDE - Please provide Links for the Libraries You used here ... Thank You ...

Errorless perfect code, simple and best max clock, how can we incluide temp as ds3231 has temp sensing ability

to change the hour to 24H format, just edit line #358 on the code, from uint8_t hour12 = hour%12 == 0? 0 : hour%12; to uint8_t hour12 = hour%24 == 0? 0 : hour%24;

THANKS MAN I APRECIATE IT MUCH HELPED

Great video sir. Really helpful and informative :)

Very good project. Really appreciate ur effort. Can u enhance the code accuracy of the clock by interfacing an ESP01 which would get NTP time from the wifi once a day and update DS3231 automatically ?

👍👍👍

Thank you for this, would be nice to add a link with a picture of wiring diagram to refer to

clock showing vertical on my horizontal generic 7219 8*8 module with IC to the top, also 1st module is to the left-1,2,3,4, time is displayed vertically in 4,3,2,1 manner.

Very impressive! Where can I find Ledcontrol.h file? I get error message when compiling: no such file😢..

sir your project is so cool :) I just want to ask about the buttons, I'm currently trying your project but there seems to be a problem with my buttons, it wont allow me to change the hr and minute format. I inserted all the wires correctly based on the instructions and diagram.What could be the problem?

Sir, i want to ask when we connect this led matrix to arduino and then we connect them both with PC to upload program, does the matrix LED turns on automatically or not. In my case, when I'm connecting both the module with PC, some part of the LED turns on and some are off. This is my first project and i have very basic knowledge about electronic and nil about coding.

Hello sir, want to use Atmega328p instead of arduino nano/uno. Please tell me which is the VCC in pin in arduino328p. Thanks in advance

Sir clock is working fine. Now I want to remove 0 i.e. 06:34 to 6:34. Please tell me how to remove 0. Thanks in advance

Does the rtc use lithium cell?

Dear sir if DS3231 shows temperature and date then why didn't you add temperature code. Sorry for my poor english. Please make one click with the same as above sai but text should be scrolling. Thanks

Sir, which software did you use in designing this clock circuit? Please tell me And also I am not finding max7219 dot matrix in tinkcard. Can you hello me. Thanks in advance

the code cannot be downloaded

👍👍👍👍👍👍👍👍👍👍👌👌👌👌👌👌👌👌👌👌👌👌

BRO PLEASE HELP HOW TO CRRECT THE ORIENTATION IT IS NOT CAMING LIKE YOU "M" CAMING TO LAST SEGMENT AND MINUTS CAMEING IN FIRST SEGMENT , IT IS ORIENTED LIKE IF IT IS 2 O CLOCK THEN SHOWING 0 0 2: 0 OR IF THE TIME IS 2:08 IT SHOWS 802:0 , OR SUPPOSED IS THE TIME IS 2: 11 IT SHOWS 112:0 AND THE MINIUTS VALUE GOSE UP TO MORE THEN 90

Sir, I do not know arduino coding please tell me if you have used software spi or hardware spi. Code is working fine. Thanks for sharing the code Please reply

the code is not available now, can u fix it?

How to include date

e sub parts kahan milenge ao prise keya hay sab ke

I made this with arduino uno. But push buttons didnt work😒😒😒😒 so cant adjust the time. How can i fix it😒😒😒😒

Brother please add date and day and tempreture that cames from rtc information to coding foe displaye

The code is not available anymore, can you fix the link please?

Im searching same but neo6 GPS time to display. Can anyone help me out?

What is the program used in programming

DS3231 Module with Arduino

Sir the code is not working, it shows ' led control h file ' is not found how to clear

The code is not available anymore, can you fix the link please Its Happening Again

error "Font_Data.h" : No such file or directory how to fix it..?

sir ji code mil sakta hie kay

NEED SCROLLING CLOCK

is there alarm

Rtc modul codeing

Sir where is the code ??

can not download code it says error 404
