Hi ! Liked the clock.
I'd like to know, does it plays alarm ? How do you set time & Date.
I've made one same type & Adjust it with Bluetooth serial connection & want to add physical button.
For ideas on how to set the time, I suggest you look at the thread for my two-button clock:
https://forum.arduino.cc/index.php?topic=408565.0My clock uses a simple, two-button system. One button moves a cursor, and the other button changes the digit over the cursor. Have you ever owned a simple, 1980's-style digital wristwatch? The procedure for setting the time on my clock is similar to the procedure for setting the time on such a wristwatch.
My clock uses a simple, 16x2 LCD character display. (This is not an LED display!) However, the
logic for setting the time is what is important, and you can perhaps adapt my code for your use.
