The BBC micro:bit is a pocket-sized codeable computer with motion detection, a built-in compass, LED display, and Bluetooth technology built in.

It measures 4cm by 5cm, is available in a range of colours, and designed to be fun and easy to use. It can be coded with something simple in seconds – like lighting up its LEDs or displaying a pattern – with no prior knowledge of computing.

It also connects to other devices, sensors, kits and objects, and is a companion to Arduino, Galileo, Kano, littleBits and Raspberry Pi, acting as a spring board to more complex learning.

Each element is completely programmable via easy-to-use software on a dedicated website that can be accessed from a PC, tablet or mobile.

It's the same shape and size so should be already familiar to countless teachers and learners, and also compatible with the vast majority of add-on boards and accessories.

How does the BBC micro:bit work?

It's programmed with beginner friendly, drag and drop interface MakeCode with the option to progress into MicroPython later on, opening up even more programming possibilities!

It's packed with inputs, outputs, sensors and radio communication features that can be combined into and endless variety of projects.

Inputs and outputs: 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.

LEDs: An LED, or light-emitting diode is an output device that gives off light. Your BBC micro:bit has a display of 25 LEDs for you to program.

Buttons: A very common input device. Your micro:bit has two "clicky" buttons and a touch sensitive button you can program, and a reset button.

Radio: A way of sending and receiving messages and BBC micro:bits can use radio waves to communicate with each other.

Accelerometer: A motion sensor that measures movement. The accelerometer in your BBC micro:bit detects when you tilt it left to right, backwards and forwards and up and down.

Compass: An input sensor that detects magnetic fields. Your BBC micro:bit has an inbuilt compass that can detect the direction in which it is facing.

Light sensor: 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.

Temperature sensor: 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.

Pins: On the bottom edge of your BBC micro:bit there are 25 gold strips, called pins. These pins allow you to really get creative. You can create circuits, connect external things like buzzers and motors and make your own fun projects.

Sound: 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.

Requires:

  • microB USB Cable for programming
  • Computer/laptop with Internet access

      Serial to Micro USB adapter for Raspberry Pi Zero (AW Zero serial adapter)

      RASPBERRY PI ZERO NOT INCLUDED

      This solderless serial adaptor for the Pi Zero adds a micro USB port to the Pi's GPIO for serial connections! The board uses an FTDI FT234X IC, and Virtual COM port (VCP) drivers are available for many operating systems on the FTDI website.

      Using solderless pins, the adapter slides onto the back of a Pi Zero GPIO with no soldering, but if a permanent connection is required, the adapter can still be soldered to the GPIO header.

      The adapter PCB is printed with an alignment guide: Ensure the white SQUARE on the PCB is aligned with the GPIO pin with the SQUARE gold pad on the Pi Zero GPIO pin 1. It's advised to connect the adapter to the Pi Zero before connecting the USB cable to the adapter, to prevent the serial RX/TX pins being connected before the ground pin. Once connected the Pi Zero can be powered on/off without issue.

      When using with the Cluster HAT you will need to cut the pins down so only a few millimeters stick through the Pi Zero and then file the ends round otherwise the adapter will short on the back of an adjacent Pi Zero. With use the pins may become worn and need adjustment to keep in good contact with the Pi Zero GPIO header.

      This solderless serial adaptor for the Pi Zero adds a micro USB port to the Pi's GPIO for serial connections!

      Relay for micro:bit (micro:bit Relay board)

      The MonkMakes Relay for micro:bit is a solid-state (no moving parts) relay that allows an output of a micro:bit to turn things on and off.

      A micro:bit can turn an LED on and off directly, but anything more powerful requires something like a relay or a transistor. Using a transistor to switch something on and off requires a shared ground connection with the micro:bit and a knowledge electronics that you or your students may not be ready for. The MonkMakes Relay for micro:bit is much easier to use, acting like a simple micro:bit controlled switch.

      This relay can be used to switch low voltage devices such as light bulbs, a motor, a small heating element or even a string of 12V LED lighting. The voltage needs to be kept under 16V, but the relay will automatically protect itself against too much current.

      FEATURES

      • Solid-sate relay (up to 2 Amps)
      • Active LED indicator
      • Resettable ‘polyfuse’ to protect against over-current

      Getting Started

      Connecting your micro:bit

      The Relay requires just two connections to the micro:bit. One to GND (ground) and one to whatever pin is to be used to control the relay’s switching action.

      When attaching the alligator clips to the micro:bit, make sure that the clips are perpendicular to the board so that they are not touching any of the neighbouring connectors on the micro:Bit edge connector.

      Here’s an example of how you could wire up a MonkMakes Relay for micro:bit to turn an old fashioned light bulb on and off.

      HEX File

      The quickest way to try out your relay is to DOWNLOAD THIS HEX FILE >and then copy it onto your micro:bit. The program will turn the relay on and off once a second.

      JavaScript Blocks Editor

      Set the controlling pin to 1 and the relay contacts will close, set it to 0 and the contacts will open again. Its as simple as that. So, to make your relay turn on and off once a second, open the Blocks Editor, add a forever block and then the digital write blocks from the pins category and the pauses from the basic category.

      MicroPython

      Paste the following code into the Python window and then Download the file and copy it onto your your micro:bit.

      from microbit import *

      while True:
          pin0.write_digital(True)
          sleep(500)
          pin0.write_digital(False)
          sleep(500)



      Analog Outputs

      The latest MonkMakes Relay for micro:bit can do more than just switch things on and off. It can also be used with micro:bit analog outputs. Look closely at your Relay for micro:bit and is it has the version number v1ev (under the word ‘Board’) then it can be used with the ‘analog write’ block in the blocks editor or the ‘write_analog’ function in MicroPython. If your board has the version number v1e then it is not suitable for use with analog outputs – sorry you were unlucky to get one of the small batch of first boards to be sold.

      The output of the Relay for micro:bit is not linear at low PWM and high PWM values as the following chart illustrates.

      The y-axis shows the current in mA for a test load resistor supplied from a constant voltage source. The x-axis is the analog write value (0 to 1023). As you can see, there is a dead zone up to a analog output value of about 100, followed by a relatively good linear region right up to about 1000, after which the output effectively becomes ‘on’.

      The tests were carried out at the default PWM frequency of 50Hz for the micro:bit. Lower frequency PWM is expected to produce more linear results.

      The MonkMakes Relay for micro:bit is a solid-state (no moving parts) relay that allows an output of a micro:bit to turn things on and off.
