PWM Method to varies Duty cycle using PIC Controller

In this project we want to control the duty cycle of a waveform to control the switching time of BJT for converters, in SMPS (Switched Mode Power Supply), to control speed of DC motor likewise examples. In this project duty cycle change from 1% to 99%. Here are proteus results. 

Here are some learning points for Students:

• 1.       How to read analog values
• 2.       How to program ADC for analog values
• 3.       How to program PWM
• 4.       How to see oscilloscope results in proteus
• 5.       How to use built-in libraries of MikroC

List of components:

• 1.       PIC16F877A
• 2.       Crystal 10MHz
• 3.       Non pol capacitors 33pf
• 4.       Resistors
• 5.       BJT 2N3904
• 6.       LED
• 7.       Potentiometer
