EXPERIMENT BOX for the BBC micro:bit

The EXPERIMENT BOX provides an excellent starting kit for learning about connecting sensors, LEDs and other devices to the BBC micro:bit.  It is ideal for beginners who have no experience of connecting or controlling external components.  You can create it by purchasing the Kitronik Discovery Kit and Kitronik ZIP LEDs pack, together with some extra sensors.  The simple breadboard, together with a range of LEDs, a piezo speaker, sensors, resistors and jumper wires, makes it easy to build simple circuits with no previous skill.  With Mr Bit files you quickly discover how a simple program makes the micro:bit become a powerful controller.


The ready-made files below offer solutions for basic experiments and  more.  They may be downloaded directly into Insight Mr Bit, or you if download the free Mr Bit Lite, all the files are built-in and available.

Mr Bit ZIP Experiments - Further experiments which show the range of possible effects with the Mr Bit programming tools.

The Kitronik Discovery Kit contains the breadboard and breakout connector for the micro:bit which are used for all the experiments.  Consult the Kitronik Tutorial Book for details of how the breadboard works and the basic setting up instructions. For each experiment you will plug particular components into the board and use jumper wires to complete the circuit connections to the micro:bit.  The wiring diagrams are shown on your computer in the Mr Bit coding editor when you load the experiment files shown below.

Points to note:


MICRO:BIT         TEMPERATURE SENSOR

CONNECTOR               LIGHT SENSOR (LDR)       

                DIODE - Look out for the flat edge.

The Kitronik ZIP LEDs pack contains addressable RGB LEDs capable of showing any colour in the spectrum.  The LEDs are fixed on circuit boards in the shape of a stick and ring.  They require a higher voltage than the micro:bit and this is supplied by the extra battery pack. They fit very conveniently on the breadboard with wiring as shown here.  The wiring diagrams are shown on your computer in the Mr Bit coding editor when you load the experiment files below.
