Smart Conveyor Monitoring & Control System (Proteus Simulation)
Project Overview
this project simulates a smart conveyor system using an ARM Cortex-M microcontroller . the system measures conveyor speed using timer capture , controls motor speed via a potentiometer , detects passing objects , and displays all relevant information on an LCD . it also includes an emergency stop feature triggered by an interrupt .

System Requirements & Constraints

1. Speed Measurement (Timer Capture + Function Generator)
   ● Use a function generator in Proteus to simulate pulse signals.
   ● Measure the time between two rising edges using Timer Input Capture mode.
   ● Do not use interrupts for pulse edge detection.

2. Motor Speed Control (Potentiometer + PWM)
   ● Connect a potentiometer to an ADC channel.
   ● Generate a PWM signal based on the ADC value to control motor speed.
   ● Display the motor speed (as a percentage) on the LCD.

3. Object Detection (Software-Based Edge Detection)
   ● Simulate an IR sensor as a digital input.
   ● Implement falling-edge detection in software only (polling; no interrupt).
   ● Count each passing object and update the display.

4. Emergency Stop (Interrupt-Based Button)
   ● Use a push button to simulate an emergency stop.
   ● Detect button press via external interrupt only.
   ● On trigger, stop the motor and show “EMERGENCY STOP” message on LCD.
   ● No debouncing required.

5. Display Interface
   ● Use a 16x2 LCD to display:
   ○ Conveyor speed
   ○ Motor speed (PWM %)
   ○ Object count
   ○ Emergency status
