Title: Very Easy LED Resistor Calculator
Post by: dice on January 17, 2008, 02:49:29 PM
Hey everyone,

I know not everyone know hows to calculate what resistor is needed for an IR Pen or array or what ever.
This link is a smile calculator, where you input the Source voltage, diode forward voltage, and diode forward current (mA) and it will give you the resistor that is needed w/color code.

Hope this helps.

Also a color code resistor calculator

Parallel Resistor Calculator

These are very basic tools that will help people that do not know circuitry very well.
