(MRWD) Media and Real World Data Module Overview

Media and Real World Data Module Overview

Smartphones are designed to use and store data and communicate with the world around us. Smartphones have sensors that collect real world data on various things ranging from how many steps we take to the atmospheric pressure, to your current location.  

Smartphones are also used to stream media and audio and store it on the device. Often these are shared on social media sites and different apps.  Users need to understand the privacy and security issues involved with the use of this technology.

In this module you will learn how to use the components in App Inventor to create apps that involve using media and real world data.
