Kitronik 3V Vertical Submersible Water Pump

Each of Kitronik's new ZIP sticks has 5 individually addressable RGB LED’s. Each LED can be controlled independently and all LEDs are connected using the same three wire bus. Each LED can produce a full spectrum of colours independent to all of the other LEDs on the bus. Each ZIP LED has a Red, Green and Blue element within the LED, and each of these can achieve 256 levels of brightness. This results in 16,777,216 possible output colours. Multiple ZIP LEDs can be connected to produce longer strings/strips.

The LEDs used are based on the WS2812B part which is compatible with any WS2812B driver code. They can also be coded in the MakeCode Block/Javascript editor.

Features:

Simple 3 wire connection for all LEDs.

Compatible with Adafruit NeoPixel and other WS2812B driver code.

Integrated reset circuit.

Supply voltage: 3.5V to 5V.

Dimensions:

Length: 34.3mm.

Width: 10.2mm.

Height: 3.2mm.

Hole Diameter: 2.2mm.

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.

This add-on pack for the Kitronik Inventors Kit for the BBC microbit provides the perfect way to learn about the wonderful world of ZIP LEDs. These LEDs are simple to control and can be used to produce a whole range of fantastic colours. Most consumer electronics heavily rely on LEDs, as LEDs are a great way of providing instant visual feedback for the user. With this add-on pack, you will learn how to write code to take control of ZIP LEDs and also learn how to make ZIP LEDs respond to input from components such as potentiometers and sensors. There are ten experiments, 9 in the booklet and one online, that will help you develop the skills needed to add visual feedback to your projects.

ZIP LEDs are individually addressable RGB LEDs. The name is a nod to the ZIP postal codes used in the US. Each LED can be controlled independently and all LEDs are connected using the same three-wire bus. Each LED can produce a full spectrum of colours, independently of other LEDs on the same bus. ZIP LEDs are based on the WS2812B part and are often referred to as NeoPixel’s (which is an Adafruit trademark) and are compatible with Adafruit NeoPixel and other WS2812B driver code. They can be coded for the microbit in both MakeCode Blocks and MicroPython.

Features:

Learn how to control ZIP LED colours.

Learn how to move a light through any number of ZIP LEDs.

Learn how to control ZIP LEDs independently.

Learn how to make ZIP LEDs respond to input from electronic components and sensors.

Contents:

2 x ZIP Stick - 5 LEDs each.

1 x ZIP Ring - 12 LEDs.

1 x 3 AA battery pack.

1 x Tutorial booklet.

Add some colour to your next coding project with our new Halo board for the BBC micro:bit. The Halo has 24 ZIP LEDs, which are individually addressable full-colour LEDs. This means that each LED can display a huge spectrum of colours, allowing amazing colourful effects to be achieved.

The Halo bolts directly onto the BBC micro:bit using five bolts which are secure and robust. The board also has extension connector pads (0.1” pitch) allowing more ZIP LEDs to be connected. The P1 and P2 micro:bit pins are also broken out to 0.1" pads along with power and GND. This allows for additional connections to low power components such as sensors and switches.

The Halo takes a supply voltage of 3.5V-5V and provides a regulated power supply to BBC micro:bit. Power can be connected using the JST input using a 3xAAA battery holder, LiPo battery, or JST lead. Alternatively, you can solder a power supply directly to the solder pads on the PCB. The LEDs used are based on the WS2812B part which is compatible with any WS2812B driver code. They can also be coded in the MakeCode Block/Javascript editor.
