Automated Can Filling System with STM32F407VGT6

This project implements an automated can filling system using an STM32F407VGT6 microcontroller, UART, Timer, 4×4 Keypad, DC motor, and ALCD. The system detects cans on a conveyor belt, fills them using a solenoid valve, and provides real-time status monitoring both on an ALCD and via UART.

Features

• Detect cans on the conveyor using a sensor
• Automatically stop conveyor motor when a can is detected
• Open solenoid valve for a user-defined filling duration
• Close valve and restart conveyor motor after filling
• Increment and display the number of filled cans on ALCD
• Menu system for setting time and date
• Send can count, time, and date via UART for external monitoring

Components

• Microcontroller: STM32F407VGT6
• Input Devices: 4×4 Keypad, sensor
• Output Devices: ALCD, DC motor, solenoid valve
• Communication: UART
• Timers: For precise control of motor and valve timing

How It Works

1. The sensor detects the presence of a can on the conveyor belt.
2. The DC motor driving the conveyor stops immediately.
3. The solenoid valve opens for the duration configured in the settings to fill the can.
4. After filling, the solenoid valve closes and the conveyor motor restarts.
5. Each completed fill increments the can count displayed on the ALCD.
6. The menu system allows users to set time and date via the keypad.
7. The UART interface sends the number of filled cans, current time, and date to an external system for monitoring.

User Interface

• ALCD: Shows the number of filled cans, current time/date, and menu navigation
• Keypad 4×4: Navigate menu and set time, date, and filling duration
