Intelligent LED desk lamp design based on microcontroller_with circuit diagram, finished product demonstration diagram, and source program

This article introduces the framework structure and component modules of the design as well as the principles of each module. It also introduces the hardware design of each part, the software design of each part, and the software flow chart. The design is an intelligent LED desk lamp integrating multiple functions with STC89C52 microcontroller as the control core. The desk lamp realizes the function of automatically detecting whether there is someone in the room and automatically turning on/off; the desk lamp brightness has an adjustment function; it has a time display function; it has a temperature display function; and it has an alarm function. The hardware design is divided into eight parts, including the microcontroller control module, button module, desk lamp module, temperature module, clock module, alarm module, display module, and infrared sensing module. The microcontroller control uses STC89C52, the display module uses LCD1602C liquid crystal to display temperature, time, date, etc., the button module is used to adjust time, date, LED brightness, etc., the clock uses DS12C887 clock chip, and the desk lamp module uses 16 LEDs and uses a buzzer. The device emits an alarm sound, the temperature sensor uses a DS18B20 chip, and the human detection device uses a BIS0001 infrared thermal sensor. The software design is written in microcontroller C language and realizes all control functions.

Pocket oscilloscope source code based on STM32, has been tested and passed

Solemn statement: This is an open source product and can only be used for learning and communication. Commercial use is strictly prohibited, otherwise we will pursue legal liability. Your use of our source code indicates your acceptance of this statement. Qdso is a well-designed pocket oscilloscope with 40M bandwidth, 200M sampling rate and 3.5-inch TFT color screen. The overall design controller uses nios ii soft core; AD9288-100 cross sampling rate reaches 200M real-time sampling, and the display part uses RA8872 that supports double buffering and 2D drawing acceleration to achieve high-speed waveform drawing and display. And we will make the source code and detailed tutorials public for everyone to DIY and learn from.
