Re: [How-To] LED Circuit

The led doesn't have a 0.7v forward voltage drop, this is the voltage for a normal silicon diode.

Leds have a Vf that depends on the color and type
Light Emitting Diodes (LEDs)

The current in your circuit is (Vsource-Vled)/Resistor and not Vsource/Resistor.

Try using a 350r resistor you will see it better
