Help: Time-adjustable digital clock based on single-chip microcomputer [Copy link]

Help: A time-adjustable digital clock based on a single-chip microcomputer

requires the following functions:

key input LED digital tube display

Design a digital clock based on a single-chip microcomputer with adjustable time. The system is required to display hours , minutes and seconds. The time adjustment method is determined by yourself . You can use key input , keyboard input , or knob input .

If anyone can give me some help, I'd be very grateful! ! Thank you! !

Wow, this is just a small thing, but you are too impatient. You haven't figured out the key part yet, but you want to build the whole system. You can do the display test, key test, and timer test separately. Then combine the above three, and you will have an electronic clock. When building something, you must not be impatient or anxious, but proceed step by step!!!

Why not borrow a book and read it? Now that people have said it, I don’t think I can do it!
