#The 8th Lichuang Electronic Competition#Desktop Clock

Note: * is a required field,
please fill it in during the registration stage↓
 
* 1. Introduction to project function
This is a clock, a small desktop ornament, with an alarm clock function
.
Note: The theme is not limited, it can be a solution to a problem in life/work, a solution designed for a certain group of people/scene, a graduation project/course design/DIY project/purely cool project, etc. Mainly talk about what problem you solved by what means.
 
*2. Project attributes
Please enter the content...First public original
 
Note: Please indicate whether the project is publicly disclosed for the first time; whether the project is original; whether the project has won awards in other competitions, if so, describe the details of the award; whether the project has participated in the defense at school.
 
* 3. Open source agreement
Please enter the content...
 
Note: Altruism is self-interest, please read the following content carefully.
Embrace open source and give unlimited value to the project. It is recommended that more than 80% of the core functions of the project be open source;
if a part of the function is irreplaceable and the project cannot solve the corresponding problem after deleting it, then the function implemented by this part is the core function of the project; for example, if an electronic load is designed and a host computer software is designed to monitor power changes, the electronic load is the core function and the host computer software is an auxiliary function; for example, an isolated 485 module is used in the electronic load to communicate with the host computer, then the communication function implemented by this 485 module is an auxiliary function;
the project should choose an open source protocol that suits it. If the project references other open source projects, the source should be indicated and the original author's open source protocol should be followed; the original project is recommended to use the GPL3.0 open source protocol;
the functions directly referenced from the original circuit or original code of the open source project cannot be used as the core functions of your own project, and the functions directly implemented using the general modules on the market cannot be used as the core functions of your own project.
 
Please fill in the following in the competition stage↓
 
*4. Please enter the content for the hardware part
...
Copy the tutorial in the group Note: It is recommended to use Jiali Chuang EDA. If you choose other EDA tools, please upload the schematic diagram in PDF format, the PCB drawing in PDF format, and the PCB file in Gerber format in the attachment.
