Introduction to Ultrasonic Radar: The functionality of Arduino is truly powerful, allowing for the creation of interesting projects using various sensors. Today, we will develop an ultrasonic radar using the Arduino board and ultrasonic sensor, capable of detecting distances up to 40CM. When there are obstacles, the scanning interface will display red and show the … Read more
PIR Motion Sensor The PIR motion sensor, also known as a human infrared sensor, is widely used in fields such as anti-theft alarms, visitor notifications, and non-contact switches. Piezoelectric ceramic dielectrics can maintain a polarized state after polarization, known as spontaneous polarization. Spontaneous polarization decreases as temperature increases and drops to zero at the Curie … Read more
The proximity sensor is used to detect the presence of nearby objects. For example, the LJ12A3-4-Z/BX inductive proximity sensor is a compact, low-power, user-friendly, and stable proximity switch sensor used to detect the presence of metal objects. The LJ12A3-4-Z/BX has three pins, two for connecting to a 6-36V power supply, and the third is a … Read more

PCB Design Considerations for RK3588 VDD_LOGIC Power Supply 1. The copper width for VDD_LOGIC must meet the current requirements of the chip. The copper connected to the chip’s power pins should be sufficiently wide, and the path should not be too severely interrupted by vias. It is essential to calculate the effective line width and … Read more
What is a Microcontroller?A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system. It combines a microprocessor, memory, and input/output peripherals on a single chip. The early applications were primarily in teaching microcomputer principles and simple measurement and control systems, but they are now rarely used. The Intel … Read more
(Give DotNet a star to enhance your .Net skills) Source: Dongxia Dugu cnblogs.com/tcjiaan/p/14547950.html Introduction A small fan is essentially a motor with blades attached to its shaft. There are two-blade and three-blade designs. We played with these as kids; solar-powered hats had small fans, and when riding bikes to school, they would spin in sunlight. … Read more
The idea for Nano began in the summer of 2013 when it was still called “Egg Yolk.” The initial concept was to create an entry-level self-balancing car (because I signed up for the balance group in the school’s Freescale competition, and I was preparing for it). The preliminary idea was to make it based on … Read more
