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 ...

多数のLEDを手軽に光らせたいと思ったことはありませんか? 我々はたびたびそう思います。そんなときに使うのがArduinoとTLC5940です。 TLC5940はテキサスインスツルメンツのLEDドライバICで、1チップで最大16個のLEDを制御できます。各LEDを定電流で発光させる ...

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 ...

The good thing about computers is they do your work for you, right? If you are a programmer, that doesn’t always seem to be a true statement. [Runtimemicro] has the answer, at least if you are writing ...

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 ...

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 ...

Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using the ...

From your very first blinking LED to dazzling multi-color sequences, Arduino makes it easy to bring light to life. With just a board, a few LEDs, and some code, you can experiment with patterns, ...
