    History of the microbit

    Various people in England have acknowledged the need for for computers and coding in the curriculum.

    In the 80's the BBC released a computer called an Acorn for schools and backed it up by a series of TV programmes to teach kids how to use them.

    Recently, the BBC revived it's interest and supported the development of the microbit. 

    The BBC micro:bit is a pocket-sized codeable computer with up to one million BBC micro:bits delivered for free to every year 7 student in England and Wales, year 8 student in Northern Ireland and S1 student in Scotland in 2017.

    The microbit is available commercially and the profits go to help fund curriculum and teaching resource to help teachers and students learn to code.

    Other hardware solutions available in schools include the arduino and raspberry pi

    There are many other solutions such as Scratch, Makey-makey, Hour of Code, ect. BBC British Broadcasting Corporation

      Barefoot computing

      Now funded and run by British Telecom in partnership with Computing at School (CAS), Barefoot was created by British Computer Society, The Chartered Institute for IT and the Department for Education in 2014 as a one year programme to help primary school teachers across England prepare for the changing computing curriculum. The content was developed by teachers for teachers and this continues today.

          Thermistor

          A thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors. The word is a combination of thermal and resistor.

          Thermistors are used as temperature sensors. They can be found in every day appliances such as fire alarms, ovens and refrigerators. They are also used in digital thermometers and in many automotive applications to measure temperature.

          Thermistors are highly accurate (ranging from ± 0.05°C to ± 1.5°C), but only over a limited temperature range that is within about 50°C of a base temperature. The working temperature range for most thermistors is between 0°C and 100°C. Class A thermistors offer the greatest accuracy, while Class B thermistors can be used in scenarios where there’s less need for exact measurement. Once the manufacturing process is complete, thermistors are chemically stable and their accuracy does not change significantly with age.

                  Assignment

                  If you go down to the beach at night, you will see a line of blinking lights. These are bouys that indicate a channel that ships can use and not crash into the reef. 

                  Model this by writing code so ships can see which bouy they are passing.

                  Use binary numbers to indicate which number each bouy iin a  chain of eight, and use two start bits for ech bouy.

                      Buoy Assignment

                      This is a picture of a navigation buoy off the coast near North Fremantle. A series of these guides the ships into the harbour, away from the many reefs off the coast.

                      At night, you can identify individual buoys by the sequence of a flashing light on top of the bouy.

                      Your assignment is to write a program for the first eight buoys starting at the Fremantle heads (the entrance to the harbour) back towards Whitfords. Use the binary numbers from 1 - 8, and a start code of two quick flashes. You will be allocated a number for your buoy.

                      Steps

                      Open your Scratch Google doc.

                      Create title, aim, background method, results, 

                      For background, cut and paste instructions.

                      For method, grab a screen shot of your code

                      For results, take a photo of your project.

                        • Bluetooth USB connectivity
                        • a display consisting of 25 LEDs,
                        • two programmable buttons,

                        and can be powered by either USB or an external battery pack. The device inputs and outputs are through five ring connectors that are part of the 23-pin edge connector.

                        It can be coded through a variety of languages including micro:pi and javascript.

                        This course will focus on Scratch 3.0. a block coding language.

                                  A feedback loop is a biological occurrence wherein the output of a system amplifies the system (positive feedback) or inhibits the system (negative feedback). ... Feedback loops can also occur to a larger degree: at the ecosystem level, a form of homeostasis is maintained.

                                  How does this help you in your analysis?

                                                      BBC micro : a bit of history

                                                      The British Broadcasting Company has a history of educational involvement. It produced a series of lessons when computers were first being introduced to schools.

                                                      The Computer Programme was a TV series, produced by Paul Kriwaczek, originally broadcast by the BBC (on BBC 2) in 1982. The idea behind the series was to introduce people to computers and show them what they were capable of.

                                                      The Computer Programme logo.jpg
                                                      The BBC wanted to use their own computer, so the BBC Micro was developed as part of the BBC Computer Literacy Project, and was featured in this series. The series was successful enough for two series to follow it, namely Making the Most of the Micro in 1983 and Micro Live from 1984 until 1987. BBC Micro Front Restored.jpg

                                                      The Micro Bit was designed to encourage children to get actively involved in writing software for computers and building new things, rather than being consumers of media. It has been designed to work alongside other systems, such as the Raspberry Pi, building on BBC's legacy with the BBC Micro for computing in education.

                                                      The BBC planned to give away the computer free to every year 7 (11- and 12-year old) child in Britain starting from October 2015 (around 1 million devices).
