Introducing an application solution for Bluetooth products that is very common in everyone's life, a Bluetooth selfie stick application developed based on the MM32W series.
Fully automatic washing machine program and circuit diagram
An air purifier based on stm32f103rct6 chip can measure temperature and humidity and control fans.
PICO DSP is an open source, Arduino-compatible ESP32 development board for audio and digital signal processing (DSP) applications. It provides an extensive audio processing feature set in a small, breadboard-friendly device, providing audio input, audio output, a low-noise microphone array, integrated test speaker options, additional memory, battery charge management and ESD protection all on a single micro PCB superior.
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.
Kinetic Digits is a mechanical flipping digital display, consisting of 448 7-segment digital tubes, simulating the effect of water flow. For various effects, it can be produced with the help of the provided host computer.
Based on STM32 crowd positioning, speed-adjustable smart fan design (program, design report, video demonstration).
The current demonstration is running on RP2040, using one of the M0 cores as the GPU.
Multifunctional mini computer (SD, wifi, OLED) design source code and related test programs
icebreaker++ is a very nice and convenient little board. But it has a small flaw, the ice40 FPGA it uses is very simple, and it's generally fun to see people doing exciting projects with 5k LUTs. Sometimes it's convenient to have some extra space available when experimenting.
51 microcontroller countdown 120 seconds C program
Hardware configuration: Dialog Semiconductor DA14683 for master control, with BLE5.0
The main function of the electronic perpetual calendar is to display the Gregorian year, month, day, week, [hour] hour, minute, second and the lunar month and day. When displaying the lunar time, it can indicate whether it is a leap year.
