What is it?
Is it like a raspberry pi?
Not really. It’s similar, but the Raspberry Pi is a computer by itself, and it runs an operating system of its own. For example, you can just plug a keyboard and mouse into the raspberry pi and use it like any other computer, but to program the micro:bit you have to connect it to a computer. The micro:bit is a microcontroller like an Arduino. A microcontroller is a simple processing device that doesn’t have an operating system, and can only run 1 program at a time.
What can it do?
With the micro:bit’s LED display, its 2 programmable buttons and its sensors, the possibilities are almost limitless. Here are just a few beginner project ideas: A number guessing game, a rolling ball game, a magic 8 ball or even a music player! (Before attempting any of these go to Getting started with your micro:bit pt.1)
Why is there a battery pack?
The battery pack holds 2 AAA batteries, but only works with Carbon Zinc or Alkaline batteries. The battery pack plugs into the white battery connector on the back of the micro:bit, and powers your micro:bit without the need for a tethered computer.
