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

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

DIY Arduino Music Spectrum Analyzer with 280 LEDs

MAKER: emdee401／Translated by: Fun Endless

Adding dynamic LED effects to music can enhance the immersive experience of listening to music. Here, I will create a super-sized 14-frequency audio spectrum analyzer using Arduino and the Si5351 clock signal generator.

The LED strip (containing 280 LEDs) and acrylic board are the main components, with Arduino serving as the controller, equipped with microphone input, brightness adjustment, sensitivity conditions, and peak delay adjustment functions. It can

Getting Started with Arduino UNO: A Comprehensive Guide

The Arduino Uno was released on September 25, 2011, at the New York Maker Faire. The latest official version is the Rev3, known as the Arduino Uno R3. All experiments in this book are based on this version. The Arduino Uno is based on the ATMEL AVR microcontroller ATmega328p, where the letter 'p' indicates low-power picoPower technology. The microcontroller on the Arduino Uno board is installed in a standard 28-pin IC
