long current_time = millis(); //millis() - Returns the number of milliseconds since the Arduino board began running the current program. bool btn = digitalRead(BTN ...

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 ...

This project demonstrates how to control the brightness of an LED using Pulse Width Modulation (PWM) on an Arduino Uno. The LED smoothly fades in and out by changing the PWM duty cycle on digital pin ...

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 ...

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 ...

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 ...

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 ...

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 ...
