1. Main functions:
Puzhong development board experimental design
Design of electronic clock and alarm clock based on 51 microcontroller.
1. This design uses DS1302 as the clock source, and the digital tube displays hours, minutes and seconds.
2. You can set the hours, minutes, seconds and alarm clock through the buttons.
3. When the time reaches the set alarm time, the buzzer will sound an alarm.
4. The effect can be achieved on the Puzhong development board, both simulation and development boards.
(Currently only fully compatible with Puzhong development board A234, other Puzhong development board models may require code modification or wiring)
It should be noted that the 51 microcontroller chips in this design simulation are compatible. AT89C51 and AT89C52 are the specific models of the 51 microcontroller, and the cores are the same. In the same schematic diagram, both stc and at are the same, the pin functions are the same, the programs are compatible, and the chip can be replaced with 51 microcontroller chips such as STC89C52/STC89C51/AT89C52/AT89C51.

3. Design specification (report)
This design aims to realize the Proteus simulation design of a multifunctional digital clock alarm clock through 51 microcontroller. This design includes a variety of functions, such as timing, time display, time setting, alarm setting, and alarm elimination. By using the internal timer of the microcontroller, we can achieve accurate timing functions, and use an eight-bit digital tube to clearly display hours, minutes, and seconds. In addition, users can also adjust hours, minutes, and seconds through addition and subtraction settings, making the time display more flexible.
In addition, this design also has an alarm clock function. The user can set a specific time. When the set time is reached, the buzzer will sound every 1 second for 6 seconds to remind the user to get up or remind other matters. This alarm clock function can help users overcome the trouble of being late or missing important events.
In general, this Proteus simulation design of a digital clock alarm clock based on the 51 microcontroller combines a variety of practical functions and aims to provide users with a convenient and practical time management and reminder tool.
Finally, this design will use Proteus simulation software to simulate the actual working effect of the system. Through simulation testing, the reliability and stability of the system can be verified and whether there are potential problems and defects. If the test results are as expected, then this design can provide an effective reference for practical applications.
