* This sketch shows you how to drive a 12V LED strip using a TIP122 Darlington transistor. * The sketch makes the strip LEDs to fade on and off using Pulse Width Modulation. * Use any PWM-capable pin ...

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 ...

今回は、ブレッドボードにLEDや抵抗を設置し、3色LEDを光らせます。LEDを光らせるために、LEDの簡単な構成と光らせる手段である、PWM (Pulse Width Modulation) について説明をします。 LEDとは：アノードとカソード LEDは、＋極、－極の代わりに、アノードと ...

The real-life closeup image of a WS2812B LED is given below. You can see that the WS2812B die is connected to 3 individual LEDs namely Red, Green and Blue using gold wires. The video below shows the ...

しばらく使わなかったので、スケッチの描き方すらすっかり忘れてしまった Arduino UNO R3 の、基本のLチカをおさらいします。でも、ただLチカしてみるだけでなくて、プログラムを考える楽しさを思い出せたら、と思っています。 なお、スケッチの記述には ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

The art of taking long exposure photographs with blinking RGB LEDs has improved greatly over the years, mostly due to the extremely easy to use Arduino and hundreds of tutorials on the web. If there’s ...

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 ...
