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 ...

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 ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

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 ...

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 ...

The device is simple to use: just simply connect the PWM capable fans to the board, and power it using a 12 V DC power supply. The device uses an LCD screen to show information. The LCD screen turns ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...
