This paper introduces an excellent external lighting scheme for automobiles by using high power Buck LED controller. 　　Thanks to excellent lighting characteristics and efficiency, high-power LED is becoming more and more popular in automobile external lighting design. Electronic devices supporting LED must be fast, efficient and accurate to control illumination intensity, direction and focus. These

With the continuous development of social science and technology, the ecological environment we live in has been gradually destroyed, such as more and more serious haze, greenhouse effect and so on. Nowadays, our country advocates low-carbon travel. Our country spends a lot of financial and material resources to develop and use clean energy to gradually

In order to solve the problem that paper surface defects (paper defects) are not easy to identify in the production process of medical test paper, a medical test paper disease detection system based on NJ controller is designed by analyzing the main characteristics of manual detection methods and paper defects. The system is composed of

This paper designs a shunt controller based on dynamic hashing algorithm. After the remote deployment of the router is completed by using Telnet component, the traffic data of each router is acquired in time through SNMP component, and the current variables are managed. The command files are fed back to each router through TFTP server,

As the simplest structure, the highest cost and energy efficiency ratio, but the lowest reliability of the symmetrical dynamic distributed multi-rotor flight platform, the four-axis vehicle is very suitable for the training, learning and research platform of the multi-rotor aircraft. This design makes rational use of STC15 series MCU’s on-chip peripherals to deploy the necessary
