Pimoroni Display HAT Mini for Raspberry Pi

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 is the perfect speaker for projects that produce sound but where space is tight or where the speaker needs to be discreet. These speakers work well with the BBC microbit; you can code the microbit to play music or emit a beep as an alarm and this little speaker will do an admirable job.

This a 0.25W, 8ohm speaker is only 40mm in diameter and just over 4mm thick making it very similar in size to those found in talking greeting cards, you could even design a microbit talking greeting card that has the built in micro:bit as a present as well as part of the card.

Features:

8ohm speaker that is ideal for use with the BBC microbit.

4mm thick, making it ideal for use as a discreet speaker.
