モータは、Arduinoを使ったロボットや自動化プロジェクトで頻繁に使われる重要な部品です。ここでは、モータを正転・逆転させたり、速度を調整したりする方法を学びます。 1. モータの状態について モータには以下の4つの基本状態があります： 正転 ...

今回は、Arduino UNO R4を使ってLEDを調光する方法を解説します。 PWM*とは、👆のようなオン・オフを繰り返すような信号のことです。 *Pulse Width Modulation：パルス幅変調 またPWM信号の1つのサイクル（周期）に対して、オンの時間がどれだけあるかを示した比率 ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

このリポジトリは、Arduino UNO R4 (RA4M1) でPWM信号を生成する色々な方法を示しています。 例は単純なものから高度なものへと進み、複雑さが増えますがユーザーができる制御レベルも向上します。 This repository demonstrates different methods for generating PWM signals on the ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

This repo demonstrates how to work with an Arduino's PWM outputs in a clean programmer-friendly way. It packages all the low-level interaction with timer clocks that underly PWM functionality, ...

Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using the ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...
