Program Milo (tilt messages)
Create (continued). This program watches the tilt sensor and sends two different signals:
- Tilt the arm down → the Smart Hub's LED turns red.
- Tilt the arm up → a text message appears on the screen.
- Return to flat → signals clear.
Prompt: what other signals could Milo send? Different colours? Sounds? What might each one mean?
Mission program. Press Start. Milo watches the tilt sensor and sends a signal to base based on how the arm is pointed.
What you're coding towards
This is one program that keeps going round and round on the Code canvas. It waits for the arm to tilt up. Then it flashes the red light and shows a number. Then it waits for the arm to tilt down. Then it turns the light off and shows the word "Milo". Then it starts again.
