Based on STM32 crowd positioning, speed-adjustable smart fan design (program, design report, video demonstration).
This design is based on NUCLEO_F411RE as the control core, using the analog-to-digital converter inside the chip to collect external analog signals, and display the collected data with the cooperation of the TFT LCD screen. In order to facilitate visual analysis, the collected data is also drawn into a waveform graph. In order to verify its design function, a heart rate sensor is specially configured to obtain the heart rate signal. It has been actually verified that it can meet the basic requirements of the design during the acquisition process, and provides corresponding support for the generation of waveform image files. In addition, with the plug-in serial communication module, the collected data can be uploaded for deeper data analysis and processing.
PICO DSP is an open source, Arduino-compatible ESP32 development board for audio and digital signal processing (DSP) applications.

Smart curtain simulation design based on stm32, including source program and Proteus simulation files
This design mainly uses AT89C51 as the control core, which is composed of Hall sensor, LED digital picture tube, HIN232CPE level conversion, and RS232. The measurement speed system of the microcontroller and the serial communication between the PC and the microcontroller are introduced in detail. Give full play to the performance of the microcontroller. The focus of this article is to measure the speed and display it on the 5-digit LED digital tube.
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.
