Kitronik USB RGB LED Strip with Pattern Selector

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 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.

Features:

Measure soil moisture levels.

Attach to the micro:bit with crocodile clips.

Compatible with both BBC micro:bit V1 and BBC micro:bit V2.

Write code for it with any micro:bit coding editor.

Dimensions:

Length: 33mm.

Height: 43mm.

PCB Thickness: 1.6mm.

Monitor and analyse the air you breathe with the Kitronik Air Quality Board. Great for home and the classroom. The Kitronik Air Quality Board provides a complete air monitoring and reporting solution for the BBC micro:bit. The wealth of onboard sensors and connection points allow you to collect extensive air quality data that can be stored in onboard memory and displayed on the OLED screen or transferred to a computer for analysis. Kitronik has also produced online MakeCode tutorials that are designed to introduce you to all of the key features of the board, see the 'Resources section below for links.

The Air Quality Board is perfect for the classroom. Run short or long-term classroom experiments, such as; monitoring air quality throughout the year, with and without the heating on. You can then use the collected data to produce graphs and more. Alternatively, it would make a great addition to an office/workshop, let science inform you when it's time to open those windows or remind you to ventilate your work area!

The board includes an integrated Edge Connector for your BBC micro:bit to easily slot into. The onboard sensors allow readings for temperature, pressure, humidity, air quality index, and eCO2. The real-time clock (RTC) and 1Mbit of onboard EEPROM memory enable timestamped data logging and long term data storage. There are also 3 status ZIP LEDs onboard which be used for visually displaying data. 3 of the BBC micro:bit's pins (Pins 0,1, and 2) are broken out to 0.1” pitch solder pads allowing for additional sensors or outputs. There are also 3V and GND pads for providing power to these devices.

The board can be powered via either the 3xAA battery holder or the micro USB connector. The voltage supply is controlled using a power switch, with a green status LED to indicate when the board is turned on. The board also produces a regulated 3V supply which is fed into the edge connector to power the inserted BBC micro:bit, removing the need to power the BBC micro:bit separately.

The board also features a connection point for a solar cell that can be used alongside rechargeable batteries to keep your experiments running for longer. NOTE: Please ensure the correct rechargeable batteries are fitted before charging, they should be NiMh.

Kitronik has produced custom MakeCode blocks to make the task of coding as straightforward as possible. You can add our custom blocks to the MakeCode editor by clicking on the cog icon in the top right of the editor and selecting Extensions. You can then type and enter Kitronik into the search bar and then click on the tile for the Air Quality Board blocks. The custom blocks will now be added to the editor's blocks menu. These blocks can also be added to the menu via this URL; https://github.com/KitronikLtd/pxt-kitronik-air-quality

Unlock the secrets of nature with code, engineering, and the Environmental Control Board for micro:bit!

The Kitronik environmental control board provides a variety of sensor inputs and connection points for the BBC micro:bit (V1 & V2) and provides the ability to control outputs for devices such as a water pump, fan, servo or heater pad. This makes it ideal for feedback control systems. This board is also supplied as part of the Kitronik Smart Greenhouse Kit.

The BBC microbit slots directly into the board via an integrated edge connector. The micro:bit can then read input from the onboard BME 280 environmental temperature, barometric pressure and humidity sensor and also the Real-Time Clock. There is an onboard piezo buzzer, 2 x 1A outputs (ideal for a water pump, heater pads or fan), 3 status ZIP LEDs, a ZIP LED expansion connector and servo output. In addition to these, 3 BBC micro:bit pins are broken out to croc-clip connections as further inputs and outputs, along with pads for 3V and GND.

Power is provided via the onboard 3xAA battery holder or the 2.1mm DC Jack. There is an on/off switch for controlling power supply to the board and there is a green LED to indicate when the board has been turned on. The board also produces a regulated 3V supply which is fed into the edge connector to power the inserted BBC micro:bit, removing the need to power the BBC micro:bit separately.

The board also features a solar cell input and will charge rechargeable batteries if inserted into the onboard battery holder. Renewable energy is becoming increasingly important and this board can be used to help illustrate greener ways of delivering desired outcomes.

The environmental control board can be coded with the MakeCode editor and Kitronik have produced a set of custom blocks to make the job as simple as possible. There are blocks for reading input and for controlling additional devices such as a pump. This can be added via the add Extensions function in the editor by searching “Kitronik” or from https://github.com/KitronikLtd/pxt-kitronik-smart-greenhouse. The supplied datasheet has detailed coding advice, so much so that the beginner will have no difficulties following along.

The board can be coded without using our custom blocks in the MakeCode Blocks, Javascript, and Python workspaces. Coding for some of the board's features, e.g. I2C, requires an in-depth knowledge making it mainly suitable for the more advanced user.

Features:

Build automated systems that react to environmental changes, such as plant watering and greenhouse systems.

It is compatible with both micro:bit V1 and microbit V2.

The board features a number of sensor inputs that can be coded to control the board's outputs.

There is an onboard BME 280 environmental temperature, barometric pressure and humidity sensor and a separate Real-Time Clock (RTC).

The board also features an onboard piezo buzzer, 2 x 1A outputs (ideal for a water pump, heater pads or fan), 3 status ZIP LEDs, a ZIP LED expansion connector and servo output. In addition to these, 3 BBC micro:bit pins are broken out to croc-clip connections as further inputs and outputs, along with pads for 3V and GND.

It can be powered via the onboard 3xAA battery holder or the 2.1mm DC Jack, and the power controlled via the on/off switch with an adjacent LED indicator.

There is also a solar-cell input that can be used in conjunction with rechargeable batteries.

The board produces a regulated 3V supply for powering the micro:bit via its edge connector i/o connections.
