How to Connect LEDs - Parallel Circuit

This guide provides clear, practical instructions for building a safe and reliable parallel LED circuit. It explains how to calculate appropriate resistors and choose a suitable DC power source before beginning assembly. A detailed equipment list is provided, along with a warning about the hazards of sharing a single resistor across multiple LEDs. Step-by-step instructions show how to solder individual resistors to each LED, arrange the components into a parallel configuration, attach wires, connect a switch and battery snap, and insulate exposed joints. Designed for beginners, the guide helps users construct a functioning LED strip with correct polarity, consistent brightness, and safe operation.
