Before you can bring your electronics to life, you need to feed them power—wisely. In this episode of Engineer’s Grimoire, we dive deep into the essential rituals of choosing and using the right power supply for your Arduino projects, props, and paranormal gadgets. From 9V batteries and USB banks to wall adapters and voltage regulators, host Rachel De Barros guides you through each power source like a true circuit sorcerer. Learn how to avoid common mistakes, safely distribute power to multiple components, and build smarter, safer circuits—without accidentally summoning the magic smoke.
