Dummies: Electronics For

At its core, is the art of controlling the flow of electricity to perform specific tasks. While standard electrical systems (like a simple light switch) just turn power on or off, electronic systems use various components to bend that power to their will—allowing you to dim lights, flash patterns, or process complex data. The Core Essentials

Control the flow of current so other parts don't get too much power. Electronics For Dummies

Don't try to build a robot on day one. Start with a simple circuit that lights up a single LED using a 3-volt battery. At its core, is the art of controlling

To understand how any electronic gadget works, you have to grasp four fundamental "rules of the road": The "push" or pressure behind the current. Current (I): The actual flow of electricity through a path. Don't try to build a robot on day one

This is your "eyes" in the world of electronics; it lets you see invisible voltage and current.

Electronic circuits are built from a handful of standard parts, each with a unique job:
