Ep. 8: Self Watering Plants with Eirik Sverd

In this video, Michael from Programming Electronics Academy interviews Eric Fird, a college student from Norway studying automation engineering. Eric shares his journey from studying business economics to pursuing electronics and programming. He discusses his initial Arduino projects, including a home automation system using RF signals and a no pump automatic watering system. Eric emphasizes the importance of practical projects in learning and provides insights into his creative solutions.

What was Eric Fird's initial field of study before switching to automation engineering?

• Computer Science
