How to Glow an LED using PWM with PIC Microcontroller- (Part 20/25)

Pulse Width Modulation (PWM) is a technique in which the width of a pulse is modulated keeping the time period of the wave constant. One cycle has a fixed time period called ‘Period’ and a varying on time called ‘Duty cycle’. The entire wave can have two voltages levels either logic 0 or logic 1. The PWM wave is very useful in the digital systems, since this can be used to generate different voltage values ...

DC motor and Fan speed control using Pic16f877 Microcontroller using PWM(Pulse width modulation) Technique

Here is a simple project on how to control fan or dc motor speed with microchip pic16f877 microcontroller. There are numerous ways to control the speed of motor(or fan). Varying current, voltage and resistance etc. But when it comes to controlling the speed using microcontrollers. Then the PWM (Pulse width modulation) technique is most effective one. Pulse width modulation reduces the direct current/voltage ...
