How to Make a Raspberry Pi Smart Bartender

In this video, we use a Raspberry Pi 3 (you could also use a Raspberry Pi Zero) to make a smart Bartender! The bartender that can make drinks by mixing up to 6 ingredients together at the same time, so you can have anything from a rum and coke to a long island iced tea. It can be customized to make any number of drinks, can be expanded to mix more ingredients, and also has the potential for connectivity with Alexa and Google Home / Google Assistant.
The drinks can be configured on the bartender with two simple buttons and a screen, and you can add any number of drinks to the bartender's repository through the bartender's code.
Please drink responsibly.

A NOTE ON CLEANING:
After you use the bartender, you'll want to flush out the pump tubes in order to avoid bacteria growth. There is an easy way to do this in the configuration menu. Hook all the tubes up to a water source, then navigate to configure-clean on the bartender screen and press the select button. All pumps will turn on to flush the existing liquid from the tubes. I take the tubes out of the water source halfway through to pump some air through the tubes and remove all water from the pumps. Note: make sure you have a glass under the funnel to catch the flushed out liquid.
Sanitation recommendations per FDA is 1 Tbsp bleach in 1 gallon water with a contact time of 2 minutes, then rinse thoroughly for the same time (recommended weekly).
