This project is an example of how to use an eTape liquid level sensor to build a smart web-enabled measuring cup. You can use the code from this guide to help get any sensor data onto a web page using an Arduino Yun.

Some interesting ways you might extend this project include:

• Log volume or liquid level data to a cloud service such as Google Docs or Amazon DynamoDB.
• Put a water level sensor in your home's sump pump and send an SMS message when water is rising dangerously high!
• Make a web application to help you mix drinks and other concoctions with the liquid sensor.

What can you think of to do with a liquid sensor and Arduino Yun?
