PIC16F877A's PWM generation using MikroC for PIC tutorials.

Pulse Width Modulation (PWM) with PIC16F877A Microcontroller Using mikroC

Welcome to Learning Microcontrollers, your go-to resource for mastering embedded systems through real-world applications and step-by-step tutorials.

In this course, you will learn how to utilize the PWM (Pulse Width Modulation) functionality of the PIC16F877A microcontroller using the mikroC for PIC compiler. PWM is a powerful technique used for controlling the speed of motors, dimming LEDs, and managing other devices that require variable power control.

The course begins with an essential foundation in microcontroller theory, introduces you to the PIC16F877A architecture, and helps you get started with the development environment. From there, you’ll dive into practical, hands-on projects that teach you how to generate and control PWM signals for a variety of real-world applications.

What You Will Learn

• Understand what PWM is and how it works at the hardware level

• Explore the architecture and pin configurations of the PIC16F877A

• Set up the mikroC for PIC compiler and the PICKIT 3 programming tool

• Use the built-in PWM library in mikroC to generate precise PWM signals

• Control the brightness of LEDs and the speed of DC motors using PWM

• Interface input devices (like potentiometers, push buttons, and joysticks) to control output behavior

• Integrate motor drivers such as the L298N H-Bridge for motor control

• Apply PWM in practical scenarios such as throttle control and analog input conversion

Why PWM?

PWM (Pulse Width Modulation) allows digital systems like microcontrollers to simulate analog behavior. It’s essential in applications such as:

• Motor control (speed regulation)

• LED dimming

• Servo positioning

• Audio signal modulation

• Power delivery control

With mikroC’s built-in PWM library, implementing PWM-based control becomes intuitive and flexible, even for beginners. Once learned, these techniques are transferable to other microcontrollers supported by mikroC (such as PIC18, PIC12, and dsPIC families).

Course Highlights

This course focuses on practical implementations using the PWM module of the PIC16F877A. You’ll write working C code, simulate logic, and apply concepts directly to hardware using tried-and-tested examples.
