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 ...

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 ...

Usually, an MCU is considered a digital device. By default, its output voltage level can be either high or low and nothing in between. With the requirement to create an LED brightness control, the ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

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 ...

This chapter details the design and implementation of an LED brightness control project using pulse width modulation (PWM) on an FPGA. It begins by explaining the core principles of PWM, including the ...
