I purchased this on a whim while supporting teachers to implement the Digital Technologies curriculum through an integration with Science Year 6 curriculum. The year 6 teachers plan to get students to do the Smart Gardens activity with microbit code to check soil moisture and a servo (turns the straw to water the plant). So I thought a pump would be fun and asked LittleBird via email if they’d seen anyone attempt using this pump with the microbit and they replied with excellent videos and resources for this idea. I can’t wait to try it out. Awesome service! Thank you.
