In this project design and development automatic vending machine consists of driver IC, DC motors, LCD, micro controller.
Average
vending machines are commonplace at railway stations, airports,
fast-food restaurants and even in companies. Press a switch and the
machine delivers a cup of your favorite drink. This has become possible because of the use of micro
controllers, which allow compact size, higher reliability, lower cost
and multiple functionalists. This tea/coffee/soup vending machine
controller uses Free-scale latest AT89S52 micro controller chip.
The controller is programmable and user friendly. You can set the
quantity of the beverages through a button switch provided on the front
panel of the controller as per your requirements. Thus, cups of any
size can be filled at any time. But have to insert a coin in the system
then is working. What we take for granted as humans is not so easy for a
vending machine. A vending machine needs a relatively inexpensive way
to detect if a coin is real.
