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 ...

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 ...

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 ...

I wrote this when I could not find Arduino code online that could accurately and reliably read 25kHz pwm signals. For reliable PWM you must handle the following edge cases: 100% or 0% PWM signal with ...

This example is similar to the Motor example 01, but this time it spins from zero to max speed using a custom PWM frequency of 40kHz (40000Hz), what improves the ...
