Snake game design based on STM32, including program and PCB files
A project that uses a web page to remotely control the Raspberry Pi to send out infrared signals to control home appliances such as air conditioners. To put it simply, you can use your mobile phone to control it through the web page on the way home, turn on the air conditioner in advance, and set it to the required temperature. At the same time, the indoor temperature and humidity can be monitored in real time on the web page. The entire project is written based on Python's flask framework.
Supports continuous or intermittent monitoring of important biometric signals such as ECG, heart rate, HRV, PPG, SpO₂, blood pressure trend and respiration. It integrates daily use and advanced research applications.
This article designs and introduces a smart home control system based on GPRS wireless network with stm32 microcontroller as the core. This system is based on GPRS communication and can monitor the temperature and humidity status of the home in real time through wireless communication technology, and can freely control the switch operation of the home appliances. At the same time, the light intensity collection circuit is integrated, which can automatically open and close the curtain function.
With voice recognition function, you can use voice to search for weather, as well as radio, temperature and humidity, calendar and other functions.
Electronic clock module schematic diagram + PCB diagram (2012 version), if you are interested, you can download it and take a look.
The system consists of STC89C52 microcontroller, 4*4 matrix keyboard, buzzer, reset circuit and crystal oscillator circuit, relay, etc. The 4*4 keyboard is mainly used for password input and modification, buzzer alarm, reset circuit and crystal oscillator circuit with STC89C52 The single-chip microcomputer constitutes the smallest system of single-chip microcomputer. It has functions such as setting and modifying 6-digit user passwords, alarming for incorrect input, and alarming for incorrect passwords. This system is low in cost and practical in function.
With TMS320F28033 as the core, it is composed of signal amplification circuit, signal acquisition circuit, data storage and processing module, system control and display module and other parts.
High reference value, the 50-year-old work of FatFS author ChaN
This Bilibili small TV uses esp32 as the main control, lvgl GUI interface design, and is developed based on idf4.0 to support smartconfig or WeChat airkiss distribution. Its functions include: network connection display, network acquisition time, weather display, temperature and humidity collection, Fan count display, mqtt temperature and humidity upload, etc. All software and hardware are open source.
This project started with STM32F1 and now it uses STM32F3.
The system uses TI's MSP430F149 microcontroller as the core controller. This microcontroller has a 16-bit CPU integrated register and constant generator, which can maximize the code efficiency of the microcontroller. It integrates JTAG and supports online programming; two universal full-duplex Serial synchronous/asynchronous communication interface; PWM control output; external interrupt input interface. The microcontroller is responsible for sampling the bus door opening and closing signals, turning on or off the infrared counting module, recording the number of people getting on and off at each bus stop, storing the data on the number of people getting on and off at each bus stop, and transmitting the stored data to the computer.
Based on ESP32 and ATtiny861 to build a Nintendo NES game emulator handheld console with complete materials for making the project
This design is a connector for the Raspberry Pi HQ camera.
Grapevines use a lot of water and the soil dries out quickly, so they need to be watered twice a day. This project is about using an unmanned watering system to water flower pots.
It is the first open source system to achieve 70+ mAP (75 mAP) on the COCO dataset and 80+ mAP (82.1 mAP) on the MPII dataset. To match poses corresponding to the same person in frames, an efficient online pose tracker called Pose Flow is also provided. It is the first open source online pose tracker to achieve 60+ mAP (66.5 mAP) and 50+ MOTA (58.3 MOTA) on the PoseTrack Challenge dataset. AlphaPose supports Linux and Windows.
Use an idle Android phone to place it on a drone or unmanned vehicle/boat to realize wifi, 4G, 5G remote control of the drone, image transmission/data transmission/remote control integration. Supports APM and Pixhawk flight control (as long as it is compatible with Mavlink protocol), supports RTK differential GPS high-precision positioning (optional function, requires ublox NEO-M8P GPS module and Qianxun FindCM service account).
Based on STM8S003K3 microcontroller, it has alarm and chime functions and automatic light sensing function.
This design uses LM3S811 as the processor of the lubricating oil dielectric constant detection device, designs the AD5933 impedance measurement circuit, extracts capacitive reactance information from the impedance data, and calculates the change in the lubricating oil dielectric constant based on the change in capacitance to achieve lubrication control. Test the dielectric constant of oil and record the data to find out the change pattern between lubricating oil quality and dielectric constant.
