Description
Use the Circuit Playground Express with the MakeCode platform to tell you when your plant needs to be watered.
Using MakeCode, you can program the CPX to monitor different levels of "dryness" in the soil of a potted plant. The LED lights will serve as indicators letting you know when the plant needs watering. Students can experiment with different dryness levels and output settings, as well as expand the project by logging the data and exporting it into a spreadsheet.
