X1 DC Motor (i have used very small one with propeller)
Note that: I have used 10uF capacitor in order to operate system properly,otherwise i get unstable circuit.Such as LM35 values changing suddenly and fan not work properly etc.However,i recommend to connect 100uF into BASE and COLLECTOR of TRANSISTOR.(If you have electrolytic capacitor then connect the (+) node into BASE ,(-) node into EMİTTER) I have used LM35 in order to measure Temperature.As most of you know LM35 gives 10mV every 1 centigrade degree increase.For instance: if your room is 25 centigrade degree then LM35's outpu will be 250mV.Īlso i have used that formule in order to convert analog values to centigrade degree(which we can use): If u have questions about driving motor with transistor just have a look at this article and watch the video i hope you will handle it Click Here. You can use this idea in your own laptop or you can make your own ventilator for the HOT SUMMER DAYS :)
Hey guys again :) In this project i have tried to explain how to built Temperature Controlled FAN with an Arduino.īasically i have used transistor in order to drive MOTOR.
