LED Typical LED forward bias voltage: 1.5 to 2.0 V Typical currents needed to light LED range from 2 to 15 mA.
3
Turning on a Diode (1) V2 =3.3 V V1=3.3 V, LED is off. V1=0V, LED is on. This method is used by the 7-segment LED display on basys 2
4
Turning on a Diode (2) V1 =0.0 V V2=3.3 V, LED is on. V1=0V, LED is off. This method is used by the LED outputs on on Basys 2
