Remote Control Station

Whether i's for your TV, drone or video game system, most remote control systems work by sending light from the controller to a sensor that can "see" the light and turns something on or off.  

The kiind of light sent by TV remote controls is called INFRARED light.  Human eyes can't see it, but snakes, mosquitoes, and some fish and frogs can.

Loot at the front of your remote.  See that little lightbulb?  That is where the light comes from.  If your remote has an antennae, it's just sending a different kind of light (radio waves instead of infrared waves, because they travel farther than infrared).

Each button on a remot flashes a code of infrared light at a sensor on your TV (or drone or video game).  These flash codes make the device do different things.
