I bought some LEDs and im not really good on what resistor i should use. I have the specs of the leds below
Technical Spec
Source Material: InGaN
Emitting Colour: Blue
Emitting Wavelength (nm): 465-470
Size: 5mm
Intensity (mcd): 6000-8000
Viewing Angle (deg): 20
Forward Voltage (mA): 3.0-3.2
Forward Current (V): 20-30
I want to connect them to the 5V source from the 360 HDD and I was just wondering what resistors i should use. Would and 82 Ohm be ok? or 100ohm or am I completely off?
