Temperature Controlled Fan using Arduino | DHT11 + Motor Control + LCD | Embedded Systems Project
This project demonstrates an automatic temperature-controlled fan built using an Arduino, DHT11 temperature sensor, L298N motor driver, and an I2C LCD display.
The system continuously monitors the surrounding temperature and automatically adjusts the fan speed using PWM control. The current temperature and fan speed percentage are displayed in real time on the LCD.
