Smart Conveyor Monitoring & Control System (Proteus Simulation)

Project Overview

This project simulates a Smart Conveyor Monitoring and Control System using an ARM Cortex-M microcontroller.
It demonstrates key embedded system functionalities such as real-time speed measurement, PWM motor control, object detection, and emergency stop handling — all visualized through a 16x2 LCD display in Proteus.

System Features

1️⃣ Speed Measurement (Timer Capture + Function Generator)

• Simulates pulse signals using a Function Generator.
• Measures the time between two rising edges using Timer Input Capture mode.
• No interrupts are used for pulse edge detection.

2️⃣ Motor Speed Control (Potentiometer + PWM)

• A potentiometer is connected to an ADC channel.
• The ADC value determines the PWM duty cycle to control the motor speed.
• The motor speed percentage is displayed on the LCD.

3️⃣ Object Detection (Software-Based Edge Detection)

• Uses a simulated IR sensor as a digital input.
• Implements falling-edge detection in software (polling only; no interrupts).
• Each detected object increments the object counter, shown on the LCD.

4️⃣ Emergency Stop (Interrupt-Based Button)

• A push button simulates the emergency stop feature.
• The external interrupt detects button presses.
• When triggered:
  • The motor stops immediately.
  • LCD shows: "EMERGENCY STOP".
• No debouncing is required.

5️⃣ Display Interface

• A 16x2 LCD displays:
  • Conveyor Speed
  • Motor Speed (PWM %)
  • Object Count
  • Emergency Status
