This design includes Proteus simulation + program + design report + explanatory video.
1. Development Environment
Simulation diagram: Proteus 8.17 (lower versions available)
Compiler: Keil 4/Keil 5
Programming Language: C
Design Number: P21
2. Main Functions:
1. Use LCD 1602 as the display device to design the clock function;
2. Allows adjustment of hours, minutes, and seconds; after reset, the time is set to 00:00:00, and can be set to either 24-hour or 12-hour format;
3. Extended functions:
Includes alarm function, allowing alarm time to be set via buttons;
Displays year, month, day, and week; time setting considers month length and automatically sets the week;
12/24 hour format has corresponding indicator lights.
Main hardware: 51 microcontroller, DS1302, LCD1602, independent buttons, LED, buzzer.
(Currently fully compatible with the PuZhong 51 experimental board 234; other PuZhong development board models require wiring.)
Note that the microcontroller chip in the simulation is compatible; AT89C51 and AT89C52 are specific models of the 51 microcontroller, with the same core. In the same schematic, whether STC or AT, the pin functions are the same, and the programs are compatible. Chips can be replaced with STC89C52/STC89C51/AT89C52/AT89C51 and other 51 microcontroller chips.

4. Simulation
Open the simulation project, double-click the microcontroller in Proteus, select the hex file path, and then start the simulation.
While displaying the time, press the switch key to enter the setting mode; the variable being set will blink. First, set the year using the increment and decrement buttons, then switch to set the month, adjusting similarly. Continue this process to set the date, week, hours, minutes, and seconds.
After setting the clock, press the switch key to set the alarm. Similarly, adjust the alarm time using the increment and decrement buttons, and switch to set hours/minutes.
Pressing the 12/24 hour format switch allows toggling between formats. AM is displayed in the morning, and PM in the afternoon, making it easy to distinguish the time.
5. Program Code
Use Keil 4 or Keil 5 to compile; the code is commented, and can be understood in conjunction with the video.
6. Design Report
