About this project

The Barbot has been designed to hold up to 9 bottles of ingredients for making the cocktails, dispensing the correct amount from each to mix your cocktail of choice.

Cocktails can be chosen using the mobile app (available for iOS and Android) that connects to the Barbot via Bluetooth. In the app you can also enable/disable ingredients, change the position of each ingredient, edit the recipes and change the amount of each ingredient used in the cocktails and so on.

More information and the source code is available here.
