For best results and safe use of LEDs, the supply voltage should be more than
the LED forward voltage. Also, an appropriately valued ballast resistor should
be used. Without the ballast resistor, the LED will be damaged or destroyed.
The resistor value can be calculated by using the formula shown here.
