Build a smart cocktail shaker that helps you mix a drink with help from an Arduino, Android device, and kitchen scale.  An Arduino can sense the weight applied to a scale’s load cell and send it to an Android application over a Bluetooth or USB connection. Mixing a drink is as easy as following the instructions on screen; no more fumbling with measurements or spilled drinks!

This is an intermediate difficulty project which requires basic knowledge of Arduino and breadboarding circuits.  If you need a little more help, check out the project’s write up on the Adafruit learning system.
