Kitronik 3V Vertical Submersible Water Pump

The Prong soil moisture sensor for BBC microbit is a sensor board that can be directly mounted to a BBC micro:bit 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.

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. Prong and the BBC micro:bit can also be powered from the Mi:Power board to create a compact stand-alone unit.

The board has been designed so that the BBC micro:bit can be bolted on using 3 x M3 nuts and 3 x M3 screws. Place the screws through the P1, 3V and GND holes of the PCB and BBC micro:bit, then use the M3 nuts to fasten together on the back of BBC micro:bit. Alternatively, croc-clips can be used to connect between the Prong and the BBC micro:bit.

If using the Mi:Power board then additionally connecting P0 means the BBC micro:bit can sound an alarm if the soil becomes too dry. When fitted to the Prong moisture sensor, the micro:bit can be coded via any of the micro:bit editors, such as the Microsoft MakeCode editor.

Note: To ensure that the 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.

Features:

Measure soil moisture levels.

Attaches directly to the microbit.

Use in conjunction with the Mi:Power board to provide power and an audible alarm.

Code with any microbit coding editor.

The Clippable Detector board for the BBC micro:bit detects light, objects and can follow lines. The board is compatible directly with the BBC micro:bit and certain Kitronik boards, such as the Klip Motor Board.

The board works by using phototransistors to detect the reflectiveness of different surfaces. The Clippable Detector board has 3 phototransistor sensors evenly spaced out from each other. The sensors provide an analogue voltage to the BBC microbit. Five connections are required for full operation. These connections match those on a BBC micro:bit and can be attached using either bolts or croc-clip leads.

Kitronik have produced a set of custom MakeCode blocks for the Clippable Detector board. To add them to the editor, select the cog icon in the top right of the editor. Then, select Extensions from the drop down menu and in the search bar type and enter Kitronik. Pick the tile from the list and the new blocks will be added to the menu in the editor. It is also possible to use MicroPython to write code for this board.

Features:

The STOP:bit for the BBC micro:bit is the ultimate upgrade for traffic light/pedestrian crossing projects. Not only does it make coding the project a breeze, but the board is also supplied pre-assembled so you don't even need to fire up the soldering iron. Love it or hate it, variations of the pedestrian crossing project have been around for decades. When I did mine, it was on a 6502 EMMA board and coded with Assembly and it also included a level crossing. Thankfully, tapping low-level programming languages into a hexadecimal keypad is now a thing of the past. The Kitronik STOP:bit is a purpose-built accessory that can only lead to a more enjoyable project with a nicer looking end result.

With the Kitronik Compact Robotics Board, the BBC micro:bit can be used to drive 4 motors (or 2 stepper motors) and 8 servos. Coupled with 17 other I/O expansion points, this means the BBC micro:bit can very easily become the core of a whole variety of robotics projects. The board is small on footprint but big on features and connectivity. Please note, when used with a stepper motor, half-stepping is supported - but not micro-stepping.

The Robotics Board features 2 Dual H Bridge Motor Driver ICs (capable of driving 2 standard motors or 1 stepper motor each) and 8 servo outputs (capable of driving standard and continuous rotation servos), all controlled from the BBC micro:bit using the I2C protocol via a 16 channel driver IC. Kitronik's custom MakeCode blocks make using I2C easy, even for novice users.

The Link header breaks out all the usable pins from the BBC micro:bit, and is designed to allow 2.54mm pitch pin header to be easily soldered into place. The 17 available I/O pins allow other input devices, for example, sensors, or output devices, such as ZIP LEDs, to be added to the board. The I2C communication lines are also broken out (Pins 19 & 20), which means other I2C compatible devices can also be added to the board and controlled by the BBC micro:bit.

Power is provided via either a terminal block or servo style connector. The supply is then controlled by an on/off power switch to the board. There is also a green LED to indicate when the board is turned on. The board then produces a regulated 3.3V supply which is fed into the 3V and GND connections to power the connected BBC micro:bit. This removes the need to power the BBC micro:bit separately. The 3V and GND pins are also broken out on the Link header, which means external devices can also be powered.

To use the compact robotics board, the BBC micro:bit should be inserted firmly into the edge connector, with the LEDs and buttons visible from the front.

Kitronik has produced a set of custom blocks for the MakeCode editor to simplify using the Compact Robotics Board for BBC micro:bit. To add them to the editor, select the cog icon in the top right of the editor. Then, select Extensions from the drop-down menu and in the search bar type and enter Kitronik. Pick the Kitronik robotics Board from the list and the new blocks will be added to the menu in the editor.
