4 Slot Coin Operated Cola Vending Machine

The objective of this project is to design and construct a coin-operated, four-slot vending machine that can dispense cola bottles. The system combines a microcontroller-based control system, an electromechanical dispensing device, and a coin recognition mechanism. A motorized delivery system and sensors to determine product availability are installed in each slot. The coin mechanism activates the appropriate slot for dispensing after verifying the input cash. While a user-friendly interface shows transaction details and inventory status, a small design guarantees mobility. The project demonstrates how to combine programming, electronics, and mechanical components to produce an automated vending machine. Testing is done to ensure smooth dispensing, accuracy in coin validation, and dependability.
