A smart city uses technology to make life easier for people. Think of it like a robot that helps the whole city work better, from traffic lights that know when to change to trash bins that tell you when they're full.
Examples
- A smart city could tell a traffic light when to change based on how many cars are waiting.
- Waste bins in the city can signal when they need to be emptied.
- Streetlights adjust their brightness automatically depending on whether it's day or night.
