In this article, we will learn about the working principle of servo motors and how to control them using the Arduino development board and the PWM driver PCA9685. There are many types of servo motors, and their main feature is the ability to precisely control the position of the shaft. A servo motor is a closed-loop system that uses position feedback to control its movement and final position.
In industrial servo motors,

Maker education is the combination of maker culture and education, based on students' interests, using project-based learning methods, advocating creation, encouraging sharing, and cultivating interdisciplinary problem-solving abilities, teamwork skills, and innovation capabilities as a form of quality education. An important technological event of the 21st century—the sign of the rise of the maker movement—was the birth of the first
DIY Simple Mechanical Arm with Arduino
Introduction
The mechanical arm consists of Arduino, servos, and MeArm hardware. The Arduino controls the servos through programming, enabling the functionality of the mechanical arm. There are two types of servos: analog servos and

The Maker movement is sweeping the globe, and more and more development boards catering to various needs are emerging, which is certainly a good thing for Makers, not only because there are more choices, but also because prices have become more affordable.
However, faced with
Controlling one or two servo motors with an Arduino development board is very easy, but what if we want to control multiple servo motors?
In this article, we will introduce how to control multiple servo motors using an Arduino development board. Connecting multiple servo motors to the Arduino development board seems easy, but if we connect all the servos to the power pins of the Arduino, we may not have enough current to drive all the motors, causing them to not
In this article, we will learn how to use the Arduino development board to make a simple robot arm, which can be wirelessly controlled and programmed using a custom Android application. I will show you the entire process of making it, from designing and 3D printing the robot parts to connecting the electronic components and programming the Arduino, as well as developing our own Android application to control the robot arm.
