Passice components, LED, Tri color LED

In the 3 terminal tri color LEDs, the LEDs have a common ground or cathode. A positive voltage applied to either of the other two wires is used to light the corresponding LED. In order to light the green LED, current from the circuit (a few milliamperes) must be made to flow into the green anode. In this setup, the circuit will light green light. In order to light the red LED, current from the circuit (a few milliamperes) must be made to flow into the red anode. While lighting one anode, the other anode should be kept open, meaning no current should go into it.
