Introducing the BBC micro:bit

What is BBC micro:bit?

The BBC micro:bit is a handheld, programmable micro-computer – also known as a micro-controller. This is a computer that’s been shrunk down to a single chip. A self-contained system with a processor, memory and peripherals. Much less powerful than a laptop or tablet, and generally can do only one thing at a time.

It comes with a built-in 5×5 display of 25 LEDs, Bluetooth and sensors. It can be coded from any web browser in Blocks, JavaScript, Python, Scratch and more; no software required. It provides an engaging programming environment, with the ability to connect to and interact with sensors, displays, and other devices.

Why use micro-computers?

Very small
Use very little power
Good at talking to other electronics

They are everywhere. Examples include:

Digital watch
Mouse
Microwave oven
Telephones
Cars

Let’s get started

Attached USB cable to the top of micro:bit and plug in laptop USB port. The LED lights will flash and scroll the word ‘Hello’.

Press buttons as indicated by ‘A’ and ‘B’.

Shake: Fill the screen with dots.

The accelerometer can detect some of the forces that are acting on it. In this case, if you are shaking it (it can also detecting if it’s upside down) . You can write a program for micro:bit that will tell you how high you threw your it into the air!

Chase the Dot: Move the steady dot by tilting your BBC micro:bit. Catch the flashing dot. Now do it again a few times and you’re done.
