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 ...

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 ...

The table shows the pin configuration of the Arduino UNO–based robotic arm. The red (VCC) wires of all servos are connected ...

前回に続きNucleo Board STM32F303K8とArduino IDEの組み合わせでの使い方を覚えていこうと思います。今回はPWM出力です。 使い方 普通のArduinoと同じようにanalogWriteが使えます。 ひとまず、LEDが接続されているD13ピンにデューティ0x40で出力してみました。 void setup ...

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 ...

もっと使うゼ!!Arduino!! 前回に引き続き、今回もArduinoについて。前回はArduinoの基本の“キ”あたりをご紹介したが、今回は基本の“ホ”あたりを。前回紹介した作例より、ちょっぴり高度なものをいくつかお見せしたい。 イタリア生まれのマイコン（AVR ...

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 ...

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 ...

Neste projeto, é utilizado o conceito de Modulação por Largura de Pulso (PWM) para controlar a velocidade de um motor utilizando um Arduino Nano e um driver de motor L293D. Certifique-se de seguir as ...
