Micro:bit Input and Output Components

Front

What is a Flex Sensor?

Back

A Flex Sensor is an input device that detects bending or flexing. It changes its resistance based on the amount of bend.

Front

What type of input does a Photocell Resistor provide?

Back

A Photocell Resistor provides an analog input, which means it can detect a range of light levels rather than just on/off.

Front

What is a Servo?

Back

A Servo is an output device that can rotate to a specific angle. It is often used in robotics and automation.

Front

What is a Buzzer?

Back

A Buzzer is an output device that produces sound when activated. It is commonly used for alerts and notifications.

Front

What does a Push Button do?

Back

A Push Button is an input device that sends a digital signal (on/off) when pressed.

Front

What is the purpose of a Pressure Sensor?

Back

A Pressure Sensor is an input device that detects changes in pressure, often used in applications like weather stations.

Front

How does a Photocell Resistor work?

Back

A Photocell Resistor changes its resistance based on the amount of light it receives, allowing it to measure light levels.

Front

What is the difference between digital and analog inputs?

Back

Digital inputs have two states (on/off), while analog inputs can represent a range of values.

Front

What is an LED light?

Back

An LED light is an output device that emits light when electricity passes through it. It is energy-efficient and used in various applications.

Front

What is an LED grid?

Back

An LED grid is a matrix of LED lights that can be controlled to display patterns or images.
