I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

This repository contains two projects I've developed for the Arduino Uno platform. Task - Temperature-Controlled Fan: A solution to a technical challenge involving software-based PWM control.

The device is simple to use: just simply connect the PWM capable fans to the board, and power it using a 12 V DC power supply. The device uses an LCD screen to show information. The LCD screen turns ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

The simplest of fan-control schemes — an on-off switch — is simple but inefficient, because it provides more cooling than necessary most of the time. When on, the fully powered switch-controlled fan ...

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 ...
