Project planning: input → process → output — Electronics for kids

Remember

Input, process, output — “list what is sensed, what the program decides and what happens”

1. Input = what is sensed (a reading, a button press).
2. Process = what the program decides (compare with a limit, count).
3. Output = what happens (pump on, buzzer, LED, phone alert). Plan → draw → build with an adult → test.

Use it for: Planning a science-fair or school IoT project, team robotics and design-and-technology lessons.

Worked example: 🗺️ In an input → process → output plan, is “a soil moisture reading” the input, the process or the output? → input
