This article is for personal use to record the way to do servo control "Parallax Feedback 360° High Speed Servo" in ESP32 microcontrollers. What is Continuous Servo Motor? Servo motors are closed-loop systems that usually use feedback loops to control position. Because of its high torque compared to its size and ease of use, it is often used for robotics applications. I also frequently use servo..

Long-range Video When I want to integrate a camera with some robot projects, I usually use ESP32-CAM modules, which are cheap and pretty fast. However, that only works when we have wi-fi available or are close to the module during AP mode. Sometimes, we want to receive video from very remote places, and my solution for it was to use FPV modules that many drone hobbyists use. FPV modules use radi..
