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 ...

The embedded Arduino 101 input/output (I/O) pins operate at **3.3 V**, with a maximum **20 mA** DC current per pin. They are located on the inner columns of the dual ...

ここでは、アナログ信号を扱う方法を学びます。Arduinoを使うと、アナログ信号を読み取ったり、それをもとにLEDの明るさを調整したりできます。この章では、可変抵抗を使ってLEDの明るさを変えるプログラムを作ります。 アナログ信号とデジタル信号 ...

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 ...

Note: Some pins are not connected on a standard Arduino Uno R3 but still listed so you can use them if you had a custom board. It might also be possible that your ICSP header of the 16u2 is flipped ...

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 ...

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 ...

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 ...
