Semiconductors calculators 
LED series/parallel array wizard The LED series/parallel array wizard is a calculator that will help you design large arrays of LEDs.
LED series resistor calculator Current limiting resistor calculator for Led's
LED series resistor calculator These calculators work out the values for an LED current limiting resistor
LED calculator: current limiting resistor value DO NOT use LEDS without a current limiting resistor in series with the LED. The forward voltage rating is TYPICAL and can vary from part to part, so while some LEDS may work fine just connected to a battery of the proper voltage, others will be overdriven and be destroyed
