An 8051 Based Temperature Controlled Fan project

PWM is Pulse width modulation.. it helps you to control the output voltage by varying the width of a square wave pulse..

A Brief Description:

|¯¯|__|¯¯|__|¯¯|__ --->
 A square wave

|¯¯¯¯¯¯|______
<-Ton->
<-Tof->
.
<---Ttotal--->


Ttotal = ton+toff

Duty cycle d = Ton/Ttotal

if Vin is the input voltage and Vo is the o/p voltage.. then

Vo = d x Vin
where d is the duty cycle..
now if we ... Read Compelte post

RS232 Simulation?

actually speed of DC motor changes when you change the voltage of motor... and in digital world this is done with the help of Pulse width modulation.
So i think you should see this for learning about PWM.
I have no idea whether x86 processors have timers or not.. if not then it will be difficult to generate PWM, or you have to make use of some external thing to generate PWM.
Please go through this to... Read Compelte post
