By changing some values in the code, a 24-hour display is obtained with a delay of 1 second per 24 hours. By replacing the 2K2 resistor with a 10K trimmer potentiometer, the input voltage can be 5V.

Thank you Kiyani's Lab! The firmware is correct, the clock was assembled on the Arduino Uno r3, everything works. Good luck to you!

Found this wonderful code here for the big display, and I implemented it with my Arduino Uno. I solved its considerable drift in time by trimming the 500 ms delay near the end of the code. Tried several values until I got to 493ms instead of 500ms. Now, the clock loses only 1 second every 24 hours, not bad for a setup without an RTC module. Of course, I have to reset it to the current time every time I turn it on. Now, if somebody can please point me to code where this could be used with at least an alarm, or with the other features that come standard in a clock implementation such as a calendar, temperature and humidity sensor, etc. Thanks for posting this.

One more thing, after 11:59 PM the clock displays 00:00 AM. In my part of the world, it should display 12:00 AM. I am able to display the desired digits by changing two occurrences of 11 to 12, but I don't know how to code so that AM should change to PM and PM to AM after 11:59. Any suggestions on how to do that?

you will find this section in the code if(h>11){ h=0; a=!a; } change it with this if(h>12){ h=1; a=!a; }

Cannot be accurate as is. Looking at the code there are two delay(500) statements which are 500ms delays so two of them take 1 second... but the rest of the code takes time as well so the clock will lose time continuously. You either need to reduce those delay(500) to adjust or add a RTC (real time clock) to stay accurate.
