The MI:sound board is a speaker board for the BBC microbit. It features on-board; speaker, CR2032 battery holder, thumbwheel volume control and an easy access on/off switch. The MI:sound board can either be powered by the CR2032 battery (provided) or via the micro:bit USB or JST connections. It has been designed to work with micro:bit V1 and micro:bit V2.

The speaker on MI:sound can be used in conjunction with the micro:bits onboard speaker or instead of. The micro:bit speaker can be turned off as there is a command/block for that in the MakeCode editor. Why would you want to? Volume! MI:sound's speaker is loud, and the potentiometer gives you control over its volume without the need to head back into the code. Super convenient!

To use the MI:sound speaker board, the BBC micro:bit should be attached using the supplied bolts, spacers and nuts. Only Pin 0, 3V and GND need to be connected. Crocodile clips can also be used.

When assembled, the MI:sound board is connected directly to the 3V, GND and P0 connections on the micro:bit.

This FS90R Mini 360 Servo by Feetech is a great value multi-purpose micro size servo and it's ideal for use with micro-controller systems like the BBC microbit, Arduino, Raspberry Pi and PICAXE. It's miniature size also makes it great for use in radio controlled models and small robot projects.

This is a 360 degree continuous rotation servo. Its operation is very different to that of a standard servo. Instead of going to a specified angle, this servo will be static at a 1.5ms pulse (a trimmer is included to tweak this), a longer pulse gives forward rotation and a shorter pulse give backwards rotation.

The FS90R continuous rotation servo converts standard RC servo position pulses into continuous rotation speed. The default rest point is 1.5 ms, but this can be adjusted by using a small screwdriver to turn the middle-point adjustment potentiometer. Pulse widths above the rest point result in counterclockwise rotation, with speed increasing as the pulse width increases; pulse widths below the rest point result in clockwise rotation, with speed increasing as the pulse width decreases.

It comes with mounting screws and a range of horns to suit most applications. You can use any servo code, hardware or library to control these servos, so it's great for beginners who want to make things move without the need for a motor driver board. These servos are fully compatible with our Servo:Lite board which is also included in the :MOVE mini buggy kit for the BBC microbit.

The Mini Prong soil sensor is a short version of the original Prong sensor that has been specially adapted for use with the Kitronik Greenhouse Kit for BBC micro:bit. The Mini Prong soil moisture sensor for BBC microbit is a sensor board that can be connected to a BBC micro:bit with crocodile clips to monitor the moisture present in the soil. The two conductive tines are placed into the soil. Any water or moisture in the soil will conduct to give an analogue voltage that can be read by the BBC micro:bit.

Mini Prong is powered from the 3V supply of the BBC micro:bit. Use either the USB or JST connector on the BBC micro:bit to power the circuit. The board has been designed to work with croc-clips, to connect between the Mini Prong and the BBC micro:bit. When fitted to the Mini Prong moisture sensor, the micro:bit can be coded via any of the micro:bit editors, such as the Microsoft MakeCode editor. The Datasheet at the foot of this page includes technical information and a MakeCode blocks coding example.

Note: To ensure that the mini Prong moisture sensor has a long and fulfilling life, it is better to write your code to perform a moisture check every so often rather than continuously. When the check is performed continuously it promotes rapid erosion of the electrodes.

With this, the latest version of the Kitronik Bulldozer add-on for :MOVE mini MK2 for the BBC microbit, everyone's favourite little programmable robot buggy just got much better. Robots often do more than just :MOVE from A to B, and with this add-on so can :MOVE mini.

Although this add on has been designed to work with :MOVE mini MK2 it can also be fitted to the original :MOVE mini. Kitronik have produced two sets of build instructions as there is a slightly different procedure for each. The MK1 and MK2 build instructions can both be found in the resources section below.

Previously on :MOVE mini, we; drew shapes, controlled it via bluetooth, controlled it with a second microbit, and we also coded a variety of light shows. Now, it can totally lift and carry stuff too!

This self assembly bulldozer add-on kit is made from the same materials as :MOVE mini MK2, designed in keeping with the :MOVE mini aesthetic, and also comes with the servo required to move the bulldozer add-on up and down.

There is a very simple Servo:Lite board hack that enables the control of the third servo, you can find out how here. Once the kit is fully assembled, the bulldozer arm can be coded with the Microsoft MakeCode Editor.

Note: In order to use this accessory you must enable the third servo functionality to be able to connect the third servo to the Servo:Lite board, some soldering is required in order to do this. The header pins required for this are supplied with this kit. Also, enabling the third servo disables the onboard ZIP LEDs. If you undo the third servo hack and return the board to its original state, the onboard ZIP LEDs will be re-enabled. We have produced a short guide showing how to enable the third servo and how to revert this change, read it here.
