Use Python to add Multiple Servos to Your Self-watering Plant

This project will let you add an servo motor controller to your self-watering micro:bit project. The servo can be used to raise a flag or some sort of sign to indicate the status of your plant, and can even be located a few metres away from your self-watering plant!
The project can be run as a group activity, with one person programming the first micro:bit and their lab partner programming the second micro:bit. Alternatively, one person could program both micro:bits by having separate code in tabs within mu or Thonny editors.
Program a micro:bit with Python to Control a Water Pump

In this project, you will learn:
- how a relay works;
- how to use code to control a relay to turn a water pump on and off; and
- how to automate the pump based on sensor readings.
You will need:
- To have completed our previous tutorial for calibrating a moisture sensor, with the following:
- a micro:bit, computer with mu editor Thonny editor, and microUSB cable for programming the micro:bit
- a moisture sensor
Additional hardware required for this tutorial:
- 1 x submersible pump and hose to fit
- 1 x MonkMakes relay
- 5 x crocodile leads to connect everything up
- 1 x old water bottle or similar container to hold water
