PID Controller, also known as Proportional-Integral-Derivative Controller, is a type of feedback control system and mechanism used to control the regulation process of a system to reach the desired setpoint. It is a widely used control algorithm in industrial plants. The algorithm continuously calculates the error signal based on the difference between the desired setpoint … Read more
Introduction A few years ago, I heard about a creative door lock project: the user holds a sensing device and waves it in a specific manner. Once the device recognizes the action, it unlocks the door. This action becomes a form of key. I broke down this project into hardware and software components. The hardware … Read more
“Hey, Xiao Wang, your video editing is pretty good! How did you achieve those effects?” I glanced at Xiao Wang’s computer screen and couldn’t help but ask. Xiao Wang scratched his head and chuckled, “Brother Qian, I’m not really sure, I just followed the tutorial step by step.” “Oh? What kind of tutorial is that … Read more
