Introduction: Make Your Own Crude Cocktail Machine
In this project I will show you how I combined an Arduino Nano, an LCD, a rotary encoder, three peristaltic pumps with motor drivers, a load cell and a couple pieces of wood to create a crude, but functional Cocktail Machine. Along the way I will demonstrate how peristaltic pumps work and in which way they can interact with the other components in order to pump a precise amount of liquid. Let's get started!
Step 1: Watch the Video!
The video gives you a good idea of what is necessary to create your own Cocktail Machine. In the next steps though, I will present you more detailed information.
Step 2: Order Your Components!

You can get the beech plywood and the food safe silicone tube in your next home improvement store.
Step 3: Build the Enclosure!
Here you can find the plan of my enclosure and a couple of pictures. Use them as a reference to create your own housing.
Step 4: Do the Wiring and Programming!
Here you can find the schematic of the project, along with the final Cocktail Machine code and the first Test Code. Along with the included pictures, you can use them once again as a reference.
If you do not like the picture of the schematic, then you can also have a look at it here: https://easyeda.com/editor#id=397e5435ebe143e1918a...
Before uploading the code to the Arduino, make sure to include those libraries:
