Based on STM32L496 smart water cup holder

This work designs a smart water cup holder that can detect the use status of the water cup and remind users to drink water in time. By connecting to the Alibaba Cloud platform, automatic clock calibration is achieved. You can also set parameters for the water cup holder on the cloud terminal. The main work of this project is to design a beautiful interface that is pleasing to the eye. The other is to connect to Alibaba Cloud to realize cloud sharing and intelligent connection.

Intelligent desktop interactive robot based on eps32s3

This design is an intelligent desktop interactive robot. As the name suggests, it is an intelligent robot that can interact with people. A 2.4-inch LCD screen is used as an important channel for human-computer information interaction. It also has voice recognition and sound playback functions, making contactless interaction more convenient. The interface design adopts the open source LVGL 8 GUI framework and uses ESP32S3 as the main control chip. The current regional temperature can be displayed on the interface, and the sound can be broadcast through voice interaction. It also displays the dynamics of the EEWORLD forum, including the display of the daily number of posts and the total number of posts. Through voice interaction, the voice broadcast of the total number of posts can also be obtained. . And the onboard LED lights can be controlled by voice.
