The Pandora McNado smart car based on Rt-Thread is composed of chassis, drive, battery, Bluetooth, APP control, omnidirectional wheels, etc.
“Using the color of the desk lamp to show the growth rate of COVID-19 virus infections in a country or region, the display effect is more intuitive and not as stressful as chart data.”
These demos all use Adafruit's PicoDVI branch, which makes the video framebuffer look like a regular Adafruit_GFX object, which makes drawing very easy.
This article designs a vending machine based on the 80C51 microcontroller produced by INTEL.
ESP32S2 + Sharp memory LCD + prototyping area
This project uses STM32F103RET6 as the main control, and is modified based on ST's official CMSIS-DAP project to achieve offline and read-protected programming (because the project currently only has F103 series offline programming requirements, so only F103 programming is temporarily added. write algorithm).
The Power Profiler Kit II (PPK2) is a stand-alone unit that, in addition to external hardware, can measure and optionally source current on all Nordic DK boards from sub-uA up to 1A.
Based on the STM8S handheld non-contact infrared thermometer gun MLX90614 forehead temperature gun design, including schematic diagram, PCB, source program, etc.
Tetris design based on STM32, including source program, schematic diagram, and PCB files
The infrared controlled temperature alarm produced for this competition took half a month to make. It is a simple device made of AT89S52 with LCD 12864 as the display platform, including infrared remote control, temperature measurement, time display, alarm reminder and picture browsing. Infrared controlled temperature sensor.
Whether during construction or in use, civil construction projects require real-time health monitoring of the building structure, such as inclination changes, wall subsidence displacement, support pressure, concrete solidification temperature...
Traditional monitoring methods generally use on-site Wiring, manual scheduled patrols, and on-site reading with handheld instruments, the use of IoT technology is seriously insufficient. Therefore, this project will use LoRa networking and IoT technology to implement wireless and automated building monitoring applications.
The biggest feature of testing the power consumption of IoT devices is the high dynamic range, a few uA in the sleep state and hundreds of mA in the transmitting state, and it supports dynamic switching of the measurement range. The open source power meter ZS1100A has a dynamic measurement range of 1uA to 1.5A, a resolution of 100nA, and an accuracy of 1% ± 200 nA, which is very good.
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.
Snake game design based on STM32, including program and PCB files
The biggest highlight of this kit is Sony's own 6-core microcontroller CXD5602, which comes with 1.5MB of general-purpose SRAM, 64KB of backup SRAM, and a main frequency of 156MHz. There is also an M0+ core assist processor for IO control management, which comes with 256KB of general-purpose SRAM. The built-in GNSS receiver supports GPS and GLONASS. Others include 2D graphics acceleration (supporting rotation, scaling, mixing, etc.); dedicated sensor acquisition peripherals (with its own 40KB FIFO and supporting preprocessing) supporting SPI, I2C and other interface methods; DCMI camera interface and I2S audio peripherals All pretty good too.
With voice recognition function, you can use voice to search for weather, as well as radio, temperature and humidity, calendar and other functions.
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.
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.
