Controlling Multiple Servo Motors with Arduino

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

DIY Robot Arm Using Arduino Development Board

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.

Introduction

Using the sliders in the application, we can manually control

NuMaker UNO Development Board Review: A New High for Arduino-Compatible Boards

Why is Arduino so popular? To put it in one sentence, successful products are similar, while failed products each have their own failures.

Arduino is undoubtedly successful, but we won't discuss the reasons for its success; let's just look at the current flourishing situation of Arduino.

On one hand, there are Arduino's own products, including the classic Arduino UNO, LEONARDO, ZERO, ROBOT...

Below is a family photo provided by Arduino.

Controlling Stepper Motors with Arduino Development Boards

So far, I have not really delved into motors, especially stepper motors. Recently, I have been planning a project that requires relatively precise motor control, so I might use a stepper motor, but I quickly realized that I should first learn more about them. This article mainly introduces what I have learned so far.

What is a Stepper Motor?

A stepper motor is an electromagnetic device that moves in discrete steps. It has several coils that make up "phases" and drives the

Getting Started with Arduino: Hello World Tutorial

The Arduino UNO R3 development board I ordered online has finally arrived. I can't wait to run a Hello World test.

I downloaded the development tool Arduino IDE from the official Arduino website www.arduino.cc and installed it on my laptop. To save money, I didn't buy the original Italian version but instead purchased a so-called domesticimproved version(which should actually be calledmodified version for accuracy). The interface chipCH340 is different from the original version, so I also needed to download the USB

A Step-by-Step Guide to Building a PM2.5 Detector

In recent days, friends from the south have been coming to Beijing to experience the haze, and many have expressed that although the haze in the south is moist and elegant, it cannot compare to the richness and depth of Beijing's haze. I have also heard that the haze in Hebei is rough and bold, but it lacks a bit of cultural depth.

The haze must be appreciated for its accumulation; the old haze of Beijing is indeed thicker than the

This is an article introducing and popularizing Arduino.

I will use my final project from an elective course as an example to introduce Arduino.

What is Arduino?

In simple terms, Arduino is a very easy-to-use microcontroller. As long as you have a basic knowledge of C/C++, you can create a microcontroller project that can achieve many functions
