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.

Product Overview

Containing 1x micro:bit and a Quick Start Guide in a single retail pack, this is the ideal option for makers to get started creating BBC micro:bit projects and inventing solutions (requires a USB cable for programming purposes, and a battery holder & 2x AAA batteries to power your BBC micro:bit if not connected to your computer - sold separately). The micro:bit is a pocket-sized computer that you can code, customise and control to bring your digital ideas, games and apps to life. Measuring 4cm by 5cm, and designed to be fun and easy to use, users can create anything from games and animations to scrolling stories at school, at home and on the go - all you need is imagination and creativity. The micro:bit is completely programmable. That means each of its LEDs can be individually programmed as can its buttons, inputs and outputs, accelerometer, magnetometer and Bluetooth Smart Technology. The micro:bit has a website full of coding languages, lesson plans, tutorials, and fun ideas

Discontinued: 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.

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.

Sensor for micro:bit (micro:bit sensor board)

The MonkMakes Sensor Board for micro:bit allows you to sense sound level, temperature and light level.

Features

  • 3V and GND connections can be made from either side and allow you to power a second board such as the MonkMakes Relay Board or MonkMakes Speaker.
  • LED ‘power on’ indicator
  • Reverse polarity protection
  • All three sensors are analog and can be connected to pins P0, P1 and P2 using alligator clips.

Getting Started

Connecting to your micro:bit

You only have to wire up the sensors that you are actually using, but you could wire all the sensors up as shown below. The code examples below assume that pin 0 is used for sound, pin 1 for temperature and pin 2 for light. You can use any pin for any of the sensors, but remember to modify the code to match the pin you are using.

Sound

The Sensor for micro:bit uses a MEMs (microphone on a chip) and a pre-amplifier. The output of the sound sensor is connected to an analog input where it can be sampled. The sound signal varies about the 1.5V level. So, silence will produce an analog output of around 1.5V. When there is sound the analog readings will oscillate above and below the 1.5V level like this:

This is why 511 is subtracted from the readings in the code examples below.

Here is an example of using the Sensor Board to display a bargraph to indicate the sound level. Click on the image below to try it out. Making a noise into the microphone will make the LEDs dance.

MicroPython

from microbit import *

def bargraph(a):
display.clear()
for y in range(0, 5):
if a > y:
for x in range(0, 5):
display.set_pixel(x, 4-y, 9)

while True:
sound_level = (pin0.read_analog() - 511) / 100
bargraph(sound_level)

Temperature

The Sensor for micro:bit uses a thermistor to measure temperature. The temperature output from the board is a voltage that indicates the temperature. This is then measured using an analog input on the micro:bit.

The calculations for converting this voltage reading to an actual temperature are quite complicated and so the code examples here will only give a rough idea of temperature.

If you want your temperatures in Fahrenheit, then multiply the temperature in degrees C by 9, divide the result by 5 and then add 32.

This is an example of using the Sensor Board to display the temperature, try putting your finger on the temperature sensor to warm it up. You can run the example below by clicking on it.

MicroPython

from microbit import *

while True:
reading = pin1.read_analog()
temp_c = int(reading / 13.33 - 14)
display.scroll(str(temp_c))
sleep(500)

Light

The light sensor uses a phototransistor to measure the light level and produces an output voltage that increases as the light level increases. Here is a guide to the kind of light level you might get from the sensor under different conditions (0 to 1023).

  • Dark 0 to 3
  • Dimly lit room 6 to 10
  • Indoors directly under a light 10 to 50
  • Outdoors (dull day) 100 to 200
  • Outdoors (sunny day) 800 to 900

Even though the maximum analog read value is 1023, the maximum reading from this sensor is around 900.

Here is an example of using the Sensor Board to display a bargraph to indicate the light level. Click on the image below to try it out. Put your finger over the light sensor to make it dark or shine a flash-light onto it to make more LEDs light up.

MicroPython

from microbit import *

def bargraph(a):
display.clear()
for y in range(0, 5):
if a > y:
for x in range(0, 5):
display.set_pixel(x, 4-y, 9)

while True:
light_level = pin2.read_analog() / 10
bargraph(light_level)

Kitronik Motor Driver Board v2 for the micro:bit (micro:bit motor driver)

This motor driver board for the micro:bit allows two motors to be driven with forward, reverse, and stop control, and allows access to the other pins.

This board provides a simple way to add motor driving capability to a micro:bit. It allows two motors to be driven with full forward, reverse & stop control. It has terminal blocks to connect four input devices and a regulated 3V supply is fed in to the 80 way connector to power the inserted micro:bit.

In this new version, the pins from the micro:bit are now broken out to pads on the end of the motor driver board. These pads can either be soldered onto directly, or they are the correct spacing for our PCB pin headers (see image below for a close up of the new pads).

It is ideal for designs such as buggies (see below).

It includes an integrated edge connector slot for your micro:bit to easily slot into. It also features external connections to the buttons A and B inputs. This allows additional switches to be connected to the motor driver board and the state of these can then be read by the micro:bit.

Get up to speed quickly. Example Microsoft TouchDevelop code and example connections in the datasheet (below).

Features:

  • Drive 2 motors with full forward, reverse, and stop control
  • Terminal blocks for easy connection of motors and inputs
  • 4 inputs (2 analogue inputs and 2 provide external connections to buttons A and B as inputs)
