This guide will tell you how to tell the polarity (positive/anode and negative/cathode) of leds. Most often if you can not see any of these markings, a small notch or dot will indicate the negative side of an led. This also goes for markings on a board too.
- Resistors have three values that are of importance when doing basic mods. 1. Power Rating (Watts) You need to look at the power rating of resistors. This is usually seen by the size of the resistor itself. Typically, for the type of resistors we offer, the bigger the size the more power it can handle (more leds). 2. Resistance (ohms...
