This is a research/come up with ideas task. We're looking for hardware projects with Arduino that relate to subtitles. We're open to anything, since this is a "totally for fun" thing. Come up with 3 ideas.

Requirements:

• Realistic.
• Specific with parts, for example don't see we're going to use a sensor that doesn't exist :-)
• Specify if you own the hardware and know how to do it or not. This is not important, but if you do it's possible the actual building becomes another task.
