Description

The Bluetooth Controlled Automatic Drink Dispenser uses a custom created phone app which controls the cup dispenser, drink dispenser, and conveyor belt using the Adafruit bluetooth chip and mbed. The purpose of this device was to allow the user to wirelessly prepare a selected drink and have the drink move to the user after it is prepared. This prototype is a proof of concept, which can be scaled to dispense more types of drinks and move the drinks further than the current design.
