Automatic Beverage Dispenser

The purpose of our project was to create an automatic beverage dispensing device, for personal home use, that produces several different mixed drinks at the push of a button. The apparatus contains four bottles of liquid of any kind and a preprogrammed microcontroller which controls the type and amount of the liquids dispensed. Based on the combination of liquids that are currently in the apparatus, a variety of different mixed drinks are available. If a predetermined combination of liquids is used, common mixes are preprogrammed into the microcontroller and are automatically dispensed. The microcontroller operates multiple pumps which deposit the required amount of each separate liquid needed for the chosen mixture. Depending on which drink is desired, certain pumps will operate for a specific amount of time, always creating a perfect mix. A pint sized mixed drink can be made in less than five seconds, so the machine is very user friendly. All the workings of the device are housed in a locking steel box that can be hung on a wall, so the stored bottles can not be tampered with while the device is not in use. The application of our project is to safely and easily dispense mixed alcoholic beverages, juices, and caffeinated energy drinks
