With the advancement of technology, the ‘Coin Operated Milk Dispenser’ provides comfort and it fits well for its users in the era of modernization. Regulated power supply is designed to provide system with constant supply of 5 volts. The dispenser will dispense Milk only when the correct coin is inserted as well as with the placement of glass below the nozzle. The correctness of coin is detected by the coin sensor. If the condition is satisfied then a signal is given to the microcontroller and accordingly Milk pump gets activated and Milk will be dispensed. Here we put forward a fully automated coin-based Milk dispenser system using microcontroller and sensor. The system is capable of fully automated Milk/cola dispensing using motors and sensors. The system have a coin detector that is used to sense particular coins and send information to microcontroller about valid coins. On detecting a valid coin the system now sends a signal to the controller and then it starts the motor to pour Milk in glass using motor as long the glass is present. Thus, we here put forward a smart Milk dispenser system with Milk saving feature. When valid coin inserted, immediately 50ml Milk be dispensed. At the same time, it will display the Milk quantity levels.
