Program a micro:bit with Python to Control a Water Pump
BBC microbit Kitronik microbit plant microbit tutorials moisture sensor pump python soil moisture
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
