This project demonstrates a temperature-based fan control system using an Arduino Uno. The system reads ambient temperature via a DHT11 sensor and adjusts the speed of a 12V exhaust fan accordingly ...

This code is written to control a 12v 4-pin fan based on temperature readings from a dht22 sensor through pwm.This project used an arduino uno. The code assumes that the dht22 sensor's output pin is ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

Abstract: The application of sensors in smart homes using Arduino to control equipment such as lights, fans, alarms, and so on. Sensors used in Arduino include LDR, Ultrasonic, DHT11, and MQ2. LDR is ...

AC loads are everywhere around us because at least home appliances are supplied with the mains power. Therefore, we always face the situations that we want to have full control (dimming) over an AC ...

Most of North America has been locked in a record-setting heat wave for the last two weeks, and cheap window AC units are flying out of the local big-box stores. Not all of these discount units ...

If you love fooling around with electronics, building devices, and generally just tinkering with circuits and boards to find out what they can do, then you undoubtedly know — and likely love — Arduino ...

Arduino-fanciers Oomlout have put together a neat control box for the popular prototyping board, complete with five potentiometers and three switches. There's also a software app that can monitor the ...
