Learn to understand the basics of electronics.

Electronics is a study of how electricity is used. This covers so many different applications from running computers and cars to household appliances and robots. It also underpins the operation of many types of machinery used in horticultural practices. Lawn mowers to tractors and computer controlled irrigation to refrigeration of produce: equipment used by horticulturists uses electricity.

Your study in this course will provide a foundation which will enable you to better observe and understand the workings of all things that electricity powers in the world around you. This course helps you make better decisions about the electric devices you use, how to maintain and repair them, and more beyond that.

It is a fantastic foundation for further learning, formally or through experience.

Why Study This Course?

Faults in electronics can occur in any device that uses electricity. They are often unpredictable and can lead to costly downtime. Much of the equipment used in horticulture uses electronics from electrical systems in vehicles, to the electronics controlling pumps and irrigation, lighting, refrigeration and lots of other types of machinery. Having an understanding of electronics can arm you with the knowledge necessary to;

  • Troubleshoot common problems and discover why equipment is experiencing issues
  • Help with installation of new equipment such as smart sensors to control things like lights and irrigation
  • Learn about electronic principles to enhance your understanding for your own projects
  • A great start point for further study
