Description

Welcome to "Making LASER Based Security and Object Counting System" — a hands-on, beginner-friendly course where you’ll dive deep into the exciting world of embedded systems using the powerful PIC16F877A microcontroller. Whether you're a hobbyist, student, or electronics enthusiast, this course will walk you step-by-step through designing and building two real-world projects: a laser-based object counter and a laser-based security alarm system.

We begin with a solid introduction to the PIC16F877A—why it's popular in embedded applications, and how to understand and use its datasheet to unlock its full potential. You’ll learn about programmable pins, ports, and hardware setup for first-time users.

Next, we guide you through setting up the development environment. You’ll download and install MikroC for PIC and the PICKIT programmer tool, ensuring you're ready to start coding and uploading programs to your PIC microcontroller.

In the core part of the course, you will:

  • Interface a 16x1 LCD to display real-time data.

  • Connect and configure an LDR sensor to detect laser interruption.

  • Build a fully functional object counting system using a laser beam and LDR.

  • Implement a laser-based security system by adding a buzzer alarm and push button for control.

By the end of this course, you'll not only understand how to use sensors and actuators with the PIC16F877A but also how to bring all these components together to create practical and interactive embedded systems.

No prior experience? No worries! This course is designed to be easy to follow with clear explanations, schematics, and coding examples. Join now and start creating your own smart systems with confidence.

Who this course is for:

  • Anyone who have interest in making electronic projects.
