Microprocessors and Microsystems

This repository contains various embedded systems projects developed using MikroC PRO for PIC.
It includes exercises on digital logic gates, conditional programming, and more complex projects like sensor-based monitoring systems.
These projects are ideal for students or hobbyists learning about microcontrollers, ADCs, and LCD interfacing.

🛠 Tools and Technology

• MikroC PRO for PIC – to write, compile, and manage .c / .mcppi project files.
• Proteus 8.13+ – to simulate PIC circuits and LCD outputs.
• PIC Microcontrollers – PIC16F877A, PIC16F84A (common across projects).
• Understanding of digital logic gates, ADC, GPIO, and LCD interfacing.

📖 Projects Overview

1. Logic Gate Projects

• and.mcppi, or.mcppi, xor.mcppi
• Teach the basics of digital logic using microcontroller inputs and outputs.
• Example: input switches on PORTB, LED output on PORTA.

2. Conditional Logic Project

• If.mcppi
• Demonstrates decision-making in embedded C using if statements.
• Can be used to trigger outputs based on sensor or input values.

3. Intermediate Projects

• project2.mcppi, project3.mcppi, project4.mcppi
• Builds on simple logic, introducing timers, counters, or analog inputs.
• Good practice for real microcontroller applications.

4. Final Project – Gas Leak Detection

• Reads analog gas sensor input from AN0.
• Displays gas concentration in ppm on a 16x2 LCD.
• Triggers alarms (LED/buzzer) on PORTC depending on gas level:
  • 0–20 ppm → mild gas
  • 21–40 ppm → gas leak

  • 40 ppm → toxic gas

• Teaches ADC usage, LCD interfacing, and real-time monitoring.
