Hello all. I got into soldering recently as a hobby so that I could eventually Build a mame Arcade cabinet and wire it. To practice I got some basic velleman kits to practice on. I'm now at the point where I can tin wires and solder with ease. I recently bought some components wires and battery holders to start small projects. I recently made 2 Led flashlights for my 6 and 4 year old sons. I have been looking at the instructables site and come across some great ideas and was able to make some great designs with stuff you find around the house.
MY QUESTION IS:
I used a single LED (specs listed below). with "2 AA" batteries which equal "3 Volts" output.
Should I use a resistor or do I not need one. I appoligize, as I am very new to this.
Emitting color: Blue
Diameter: 10mm
Lens color: Water Clear
Wavelength: 460-465nm
Forward voltage(V): 3.2-3.4
Current(mA): 20
View angle: 30
Luminous intensity(MCD): 14,000 - 16,000
I appoligize if this has been asked before on a similar post, but any and all help is appreciated.
