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 ...

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 uses an ultrasonic sensor and an Arduino to measure distance and dynamically control the brightness of an LED. As an object moves closer to the sensor, the LED becomes brighter. As the ...

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 ...

今回は、Arduinoでの赤外線リモコンの使い方についてご紹介します。 赤外線リモコンとは、身近なもので言えば、TVやエアコンのリモコンです。 赤外線リモコンを使うには、リモコンから送られてくる赤外線信号を受信するための、赤外線受信モジュールが ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

ESP32 は Wi-Fi/Bluetooth 搭載 MCU として有名ですが、実は 産業用レベルのモーター制御が可能な「MCPWM」ユニットを備えています。 通常の LED 向け PWM（LEDC）ではなく、DC モーター・ステッピングモーター・BLDC を正確に制御するための専用 PWM です。 本記事では ...
