Another good example:

Now that I have been researching all the different uses the Arduino board and sensors has, my Youtube account has been flooded with suggested videos that are of a related subject. Below is video that was suggested and shows exactly the kind of hacking this module has been introducing us to.

With all the different possible hacks there is very little that cant be achieved. I also found this particular video useful as we as a group have decided to continue focusing on light as a varying factor. This video uses a light sensor to trigger a switch, which is exactly the kind of hack we want to use. The ideas we came up with will be posted soon.
