Once you have added the media list item for the video or web-page, click the blue triangle to open the configuration windows for touch sensing and turning on and off LEDs and other devices.
Typically, you will just click the check-box for a touch sensor.
This tells the MakerBit Media Linker app to open that particular webpage, or play that particular video when that touch sensor is touched.
However, you can also scroll down in the list of inputs, and use the Analog inputs as well. The Analog values displays are a measure of the resistance across the two connections of the sockets if a rainbow cable is connected to the blue ANALOG box of the MakerBit shield.
For example, for a photocell, the values displayed will decrease when light shines on the photocell, because the presence of light decreases the resistance of the photocell to the flow of electricity.
When the photocell is darkened, the value displayed will increase, because with lower levels of light on a photocell, the resistance to the flow of electricity goes up.
Your MakerBit projects are controlled by a media list.
A media list is a list of URLs that point to YouTube or Google Drive videos, or any other Internet-based media.
The idea is simple: Use the right-hand side web-view window to search and select digital media.
Then, use the "+" icon in the left-hand side media list to add a new item to the list.
For videos, you will need to enter the start and stop times for the part of the video that you wish to play. If you want to pay all of it, just leave the Start and End values as they are originally displayed.
For Google Drive videos, you have the option to "Play Offline", which is to say that the first time you play the video, it will be cached locally on your computer. After that, if you play the video again, you won't even need an Internet connection, because the movie data will be retrieved from storage on your own computer.
This can also be useful in classroom situations, where you want to minimize the total load on bandwidth that can occur when many people are viewing Internet-based videos at the same time.
However, the file size (maximum play time) of a Google drive video is limited to 25mb.
