# General LED Information

Here you can find tutorials on how to do things with LED lighting. Please check the other categories for a specific application of leds. This is more of a generic use guide and will show you how to wired leds in a general way that can be applied to nearly all applications out there.

1. ## How do you wire a switch?

We are going to go over the basics of how to wire a switch. Let's assume you have an LED, a power supply, and a switch. You would like to be able to hook everything up and be able to turn you LED on and off with the switch. We have a single pole single throw mini slide switch that...
2. ## How to Convert mA to Amps - Milliamps to Amps

We are going to show you how to convert mA to Amps (milliamps to amps). This is a very easy thing to do once you see it done. First of all, milliamps and amps are referring to the same things, but they are on different scales. There are 1000 milliamps in a single Amp. If you have 20mA and you...
3. ## How to Wire LEDs - 101 - Wiring LEDs in Parallel

This is the second part in a a multi-part series on how to wiring LEDs.   Wiring LEDs in parallel can be very similar to wiring single LEDs. Really, it is simply "tying" all of your single LEDs together and using a common + and - to power them. There are a couple ways to wire LEDs in parallel. One...
4. ## How to Wire LEDs - 101 - Single LED Example + Formulas

We are going to show you several ways to wire LEDs. You can use the video below to follow through this post. This is a basic understanding of how to wire LEDs, however this article will allow you to wire LEDs in 99% of all scenarios. The very basics of wiring an LED will involve your power supply (DC/Direct Current...
5. ## DIP LED Polarity of 3mm, 5mm, 10mm LEDs etc...

There are three ways to tell which side it positive or negative on an led in this fashion:Look at the long leg, that is positiveThere is usually a side or part of the led that is flat, that side is negativeIf you look inside the led you can see the larger side, which is also negative
6. ## Polarity Guide of 0402, 0603, 0805, 1206 and most all smd leds

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.
7. ## Resistor Value Color Code Chart

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...
