Make LED dimmer use PIC Microcontroller and Mikro C

In this tutorial we will learn how to make a LED dimmer circuit use pic microcontroller. In this project I am use Pulse Width Modulation technique for LED brightness control. I am use here PIC16F877A and LM16x2 Lcd display. 

You can watch the video or read the written tutorial below.

PIC16F877A Microcontroller has tow pin for PWM.

1. RC2/CCP1 (pin 17)
2. RC1/CCP2 (pic 16)

CCP means Capture / Compare / PWM . CCP module generate pule different duty cycle.

Each Capture / Compare / PWM(CCP) module contains a 16 bit register which can operate as a:

1. 16 bit Capture register
2. 16 bit Compare register
3. PWM Master / Slave Duty Cycle register.
