Traffic lights in Hong Kong were run in automatically.

1. How many parts are there in a traffic light? (e.g. including light bulbs, wires...)

2. How can each of the Traffic Light cooperate and work well together?

3. What kind of coding would be needed if a system with two traffic lights (one for people and one for vehicles) was designed?

Traffic lights are common in our daily lives and are essential in regulating the traffic flow on the roads and allowing pedestrians to cross the roads safely.

Use Micro:bit to simulate and beautify a traffic light system with two sets of traffic light.
