Coin Operated Water ATM with Bottle Dispenser

This project presents the design and development of a Coin Operated Water ATM integrated with a bottle dispenser system, aimed at providing easy access to clean drinking water in a controlled and automated manner. The system is built around an Arduino micro controller, which acts as the central control unit, managing inputs from a coin sensor and displaying information on an LCD screen. When a valid coin is inserted, the Arduino activates a relay that powers a DC water pump to dispense a predefined amount of water into a bottle. To enhance user experience and ensure smooth operation, a buzzer is included to provide audio feedback for coin validation and error notifications. The entire setup is powered by a stable power supply to maintain consistent performance. This solution is cost-effective, user-friendly, and promotes water conservation by dispensing water only upon payment, making it suitable for public places and areas with limited access to clean water.
