This video is the 4th in a series that introduces the basics of coding a Raspberry Pi. This beginners video demonstrates how to wire a Raspberry Pi to a relay to control a water pump. (These lessons assume you have some coding background. If not, visit CodeHS.Org . They provide free user-friendly coding class on Python and other languages that are fun and interactive).
This video is part of a broader "Design & Engineering" course for beginngers that looks at how to build a fully automated hydroponics system to grow one's own food during the winter months. The course includes tutorials on Fusion 360 for Mac users, Inventor for PC users, Python for coding, and circuit building and automation with Raspberry Pi.
