Hi all, I need to use 5 white LEDs connected to an Arduino Duemilanove I'm absolutely new to electronics and have no idea which resistor value I should apply to each LED. Looks like 200 ohms or 270 ohms is fine for the LEDs provided with the starter kit but for the LEDs I intent to buy, I'm not su…

Which resistor for a white LED 3,6V / 75mA ???
