The micro:bit helps you understand how computers work. When you type on your laptop or touch the screen on your phone, you’re using an input device. Inputs allow computers to sense things happening in the real world, so they can act on this and make something happen, usually on an output like a screen or headphones.
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.
