===Mixing===
The NXT receives the order and waits for a cup to be inserted or placed upon a certain spot. It takes the cup in its arm and advances slowly through the liquor alley.

At each liquor needed, the NXT stops and issues a signal either to the ARDUINO or the controller machine which then triggers the ARDUINO's port to open a magnetic valve giving way to a certain amount of liquor poured in a certain time.

Each stage is done in a similar way, until the NXT reaches the end of liquor alley.
