Mission Description
- Context: Cars are zooming by the school gate, and children need a safe moment to cross. You will create a mini traffic light to help them cross the imaginary street safely.
- Task: Build a simple “stop-go” light using an LED for red/green and a button. When the button is pressed by a “pedestrian,” the light should change color (or blink) to signal cars to stop. After a short time, it returns to the original state, letting cars go again.
- Expected Output: A child-friendly traffic light model that lights red when the button is pressed (telling cars to stop) and back to green after a pause. This helps students role-play safe crossing with a functioning light they coded themselves
Student Goal
Build a simple “stop-go” light using an LED for red/green and a button. When the button is pressed by a
“pedestrian,” the light should change color (or blink) to signal cars to stop. After a short time, it returns to the
original state, letting cars go again.
