A processor is sometimes called the ‘brains’ of a computer and your BBC micro:bit has a microprocessor inside it. It’s an essential part of your micro:bit as it runs the programs you write. Your BBC micro:bit can be programmed to make a wide variety of sounds - from single notes, tones and beats to your own musical compositions. USBs, or Universal Serial Buses, are used to connect, communicate and power computers and digital devices. The BBC micro:bit has a USB interface to allow you to connect your computer to your micro:bit using a micro USB cable and power your micro:bit. Radio is a way of sending and receiving messages and BBC micro:bits can use radio waves to communicate with each other A light sensor is an input device that measures light levels. Your BBC micro:bit uses the LEDs to sense the levels of light and lets you program your micro:bit as a light sensor

Tap the capacitive button as an input for your projects - stop/start music, start a timer, run a program or whatever you decide! Connect the BBC micro:bit to your phone using Bluetooth to take selfies without touching your phone Detects motion and direction - create games which use shaking motions or directions with the built-in sensors and compassThe BBC micro:bit is the spiritual successor of the BBC Micro of the 1980s, which itself introduced a generation of children to computing. The BBC micro:bit carries on this decades 30-year tradition and does it 18 times faster and it's also 70 times smaller than its predecessor.

A temperature sensor is an input device that measures temperature. Your BBC micro:bit has a temperature sensor inside the processor which can give you an approximation of the air temperature around it.

What happens if I need to return something?

Inputs and outputs are an important part of any computer system. As a very small computer, the BBC micro:bit has plenty of inputs and outputs to learn about and use with electrical components
