ELI5: Explain Like I'm 5

Remote control

A remote control is like a magic wand that you can use to make things work from far away. It usually looks like a small box with lots of buttons on it. You can use the buttons to send a signal to something and make it do something. For example, if you have a TV, you can use a remote control to change the channel or turn the TV on and off. You can also use a remote control to play music, control lights, and many other things.
