#The 8th Lichuang Electronic Competition# [Lichuang Electronic Competition] Desktop electronic clock project based on Renesas

Note: * is a required field,
please fill it in during the registration stage↓
 
* 1. Introduction to project functions
This paper implements the design of an electronic clock that displays time based on the Renesas R7FA2E1A72DFL chip microcontroller. It uses a four-digit 0.56-inch common cathode digital tube to display time, temperature and humidity. The DHT11 sensor is used to collect temperature and humidity. Serial port download and swd download circuits are added. It is convenient for burning and downloading programs. In addition, a battery socket is designed to facilitate timely power supply for the clock. In terms of circuit design, four buttons are added, which can adjust the hours and minutes of the time, and can also adjust the display interface of temperature and humidity. It truly realizes intelligent design.
 
 
*2. Project attributes
It has never won an award. It was made with the summer training camp.
 
* 3. Open source agreement
 Public Domain
 
 
*4. Hardware part

*5. Software part
Follow the software design of the training camp step by step, and use the open source code of the training camp.
 
Note: If your project involves software development, please upload the corresponding engineering source code in the attachment. Here you can explain in detail your software flow chart, functional module block diagram, explanation or popular science of related algorithms, source code structure, compilation environment construction and configuration, source code compilation method, program burning method, etc. It is recommended to introduce your ideas to others in the form of pictures and texts.
 
 
 
*6. Competition LOGO verification
 
* 7. Demonstrate your project and record it into a video and upload it.
