Input vs output
This is any data, signal, or physical reading that is collected from the outside world and sent into a computer system.
Input
Condition
A microcontroller acts as this vital organ for a robot, holding the programmed code and making all the computational decisions.
Sensors act as these human body parts for a computer system, allowing it to observe things like light, temperature, and distance.
eyes, ears, and skin (or the senses)
A smart car drives toward a wall. Suddenly, the brakes automatically slam down and the wheels lock up to stop the car. What type of machine component physically creates this mechanical movement?
motor (or actuator / brake actuator)
This is the final action, light, sound, or physical response that a computer system sends out into the world after processing data.
Output
In an If-Then rule, this specific word introduces the action or output that will happen only if the condition is true.

You can recognize this sensor because it looks like a tiny pair of binoculars or robot eyes protruding from a circuit board, used to measure distance using sound waves.
distance sensor
When it gets dark outside, a smart house automatically sends electricity to a tiny, colorful plastic bulb on the porch, causing it to glow bright red so visitors can see the door. What is this light-producing actuator?
LED (or light bulb)
Input
Write an If-Then rule for a smart nightlight that turns its light bulb on only when a room gets dark.
"If the room is dark, then turn on the light"? (Accept similar phrasing).
Fill in the blank to finish this simple rule for a smart video game controller: "If the player presses the jump button, then ___."
the character jumps
You can recognize this sensor because it features two long, bare metal prongs or legs meant to be pushed directly down into dirt to check if a plant needs watering.
Soil moisture sensor
Clue: A self-driving delivery robot comes to a corner and needs to turn right. The computer sends power to a mechanical part inside the front axle to physically pivot the wheels 30 degrees to the right. What is this wheel-turning part
steering motor (or electric motor)
A component that creates a loud beeping alarm sound when a timer reaches zero is an example of this (Input or Output?).
output
Write an If-Then rule for a smart greenhouse fan that turns on when the temperature rises above 80 degrees.
"If temperature > 80, then turn on the fan"?
Finish this rule for a school's automatic fire sprinkler system: "If the sensor detects smoke, then ___."
turn on the water / sprinklers

A smart home security system detects a thief trying to break in. To scare them away, the system immediately triggers a tiny speaker component on the wall to start blasting a loud, high-pitched screeching alarm sound. What is this sound-making actuator?
a buzzer or speaker
Classify both parts of an automatic grocery store door: 1) The motion detector that sees you approach, and 2) The motor that slides the glass door open.
1) input
2) output
If your code says: "If button is pressed, then beep buzzer. Else, turn on green LED." What happens when your finger is not pressing the button?
the green LED turns on
If a smart refrigerator has this rule: "If the door is left open, then beep the alarm. Otherwise, stay quiet." What does the refrigerator do if the door is closed perfectly tight
stay quiet
You can recognize this sensor because it contains a tiny, fragile microphone component on a circuit board designed to measure ambient volume levels.
Sound sensor
An automatic plant-watering device checks the soil and realizes the dirt is completely dry. A plastic tube attached to a water tank suddenly starts spinning its internal blades to push liquid through the pipe and wet the plant. What is this liquid-moving actuator?
A water pump
