Understanding PCB Manufacturing Process

Understanding PCB Manufacturing Process

PCB (Printed Circuit Board) is the support body for electronic components. It is called a “printed” circuit board because it is made using electronic printing technology.Before the advent of PCBs, circuits were composed of point-to-point wiring. This solution had low reliability because as circuits aged, line breakages could lead to open or short circuits.As electronic … Read more

Measuring Displacement Using Ultrasonic Sensors

In a recent class, I used an ultrasonic sensor in conjunction with the ESP32 IoT development board to conduct an extended experiment based on the textbook, which involved using the sensor and a computer to measure displacement. Under the camera of the smart blackboard system, I detailed the working principle of the ultrasonic sensor and … Read more

Principle of Microcontroller Clock Circuit

Principle of Microcontroller Clock Circuit

The clock circuit is an oscillator that provides a rhythm for the microcontroller. The microcontroller must operate under this rhythm to perform various tasks. Therefore, the microcontroller will not function properly without a clock circuit. The clock circuit itself does not control anything; rather, it is the program that allows the microcontroller to perform corresponding … Read more
