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 ...

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 ...

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 ...

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 ...

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 ...

以前の投稿記事で”ESP32MCU"の"Wifi", "Bluetooth"以外の機能の概略を紹介しました。 https://note.com/ya_ikegami/n/nd5f74a93c396 この記事で ...

Projects are categorized into three levels to make it easier for users to find the simple or advanced projects they are looking for. These levels include the ...

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...
