Imagine a light bulb that can talk to all the other bulbs in the city. It sends messages through invisible wires, and all the lights listen and turn on together like a team of friends playing a game.
Examples
- A single bulb can send messages to all the lights in a house like it's sending letters through a mail system.
- The bulb flashes fast enough that other bulbs can read the message like they're reading Morse code.
- Imagine your lightbulb is like a teacher, and all the other bulbs are students listening carefully for instructions.
