In this video tutorial you can learn how to control Automatic Room Temperature using AC Fan with 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.
