This guide will show you how to build a smart measuring cup which displays the volume of liquid in real time on a web page. No longer will you need to squint and guess while measuring liquids; the smart measuring cup's web page clearly shows the measured volume, and even converts between units or tares measurements like a digital scale!

The brains behind the smart measuring cup are an Arduino Yun and an eTape liquid level sensor. The Yun is the perfect platform for this project because it can read sensor data with it's ATmega microcontroller, and serve a web application (written in Python and Flask) using it's Linux-based processor. By following this guide you can even learn how to send sensor data to a web page for your own projects.
