Temperature Controlled Fan using Arduino

Temperature Controlled Fan using Arduino

Here we are going to make a temperature controlled DC fan. DHT22 sensor is used to sense the room temperature and then we adjust speed of a DC fan/motor accordingly using PWM (Pulse Width Modulation). Arduino Uno is the heart of this project and a L293D driver IC is used to drive the DC fan/motor. Components Required Arduino Uno L293D Motor Driver IC DHT22 Sensor 16×2 LCD Display DC Fan/motor 9V Battery 10KΩ Potentiometer 220Ω Resistor Breadboard Circuit Diagram Temperature Controlled Fan using Arduino – Circuit Diagram Explanation First we can connect L293D motor driver [...]
