In the modern era, radio waves control everything. From the tunes in your car driving down the road to the police radio in the car that’s pulling you over for not signaling your turn. These waves are undetectable and invisible to human senses but they make up the foundation of modern technology.

While the root of modern connected technologies may be radio waves, the underlying tech that makes radios possible is a rather simple concept to understand. Any person can make a simple radio in their home for a few bucks, which is part of the reason this foundational tech dates back to 1895.
