1. A faucet comprising: a spout;a handle;a touch control operably coupled to at least one of the spout and the handle;a proximity sensor having an active state and an inactive state;a logical control operably coupled to the touch control and the proximity sensor, the logical control including: a first mode, wherein the proximity sensor is inactive;a second mode, wherein the proximity sensor is active; anda mode indicator configured to provide a visual indication of at least one of the first mode and the second mode. 2. The faucet of claim 1, wherein the first mode is a manual mode such that positioning of the handle toggles water flow on and off. 3. The faucet of claim 1, wherein the second mode is a hands-free mode such that changes in the state of the proximity sensor toggles water flow on and off. 4. The faucet of claim 1, wherein the first mode is a touch mode such that tapping one of the handle and the spout toggles water flow on and off. 5. The faucet of claim 4, wherein tapping comprises a touch of less than approximately 250 milliseconds. 6. The faucet of claim 1, wherein the logical control further includes a mode controller that moves the faucet between the first mode and the second mode. 7. The faucet of claim 6, wherein the mode controller changes the faucet between the first mode and the second mode in response to a substantially simultaneous grasping of the spout and tapping of the handle. 8. The faucet of claim 7, wherein: grasping of the spout comprises a touch of greater than approximately 250 milliseconds; andtapping of the handle comprises at least one touch of less than less than approximately 250 milliseconds. 9. The faucet of claim 8, wherein the tapping of the handle comprises two sequential touches, each touch being less than approximately 250 milliseconds. 10. The faucet of claim 1, wherein the mode indicator comprises at least one light emitting device. 11. The faucet of claim 10, wherein the at least one light emitting device is configured to selectively display light of different colors. 12. The faucet of claim 10, wherein the at least one light emitting device emits no light when the logical control is in the first mode, and the at least one light emitting device emits a light of a first color when the logical control is in the second mode. 13. The faucet of claim 12, wherein the at least one light emitting device emits a light of a second color to indicate a low battery condition. 14. The faucet of claim 10, wherein the at least one light emitting device emits light of a first color when the logical control is in the first mode and water is toggled on, and the at least one light emitting device emits light of a second color when the logical control is in the second mode and water is toggled on. 15. The faucet of claim 1, further comprising a manual valve coupled to the handle. 16. The faucet of claim 15, further comprising an electrically operable valve configured to control water flow through the spout, wherein the manual valve is fluidly coupled in series with the electrically operable valve. 17. The faucet of claim 1, wherein the touch control comprises a single sensor electrically coupled to both the spout and the handle. 18. The faucet of claim 1, wherein the touch control comprises a first sensor electrically coupled to the spout and a second sensor electrically coupled to the handle. 19. The faucet of claim 1, further comprising an audio device configured to provide an audible indication of transition between the first mode and the second mode. 20. A faucet comprising: a spout;a handle;a capacitive sensor operably coupled to at least one of the spout and the handle;an electrically operable valve configured to control water flow through the spout;a logical control operably coupled to the capacitive sensor and the electrically operable valve; anda mode indicator including a light emitting device configured to provide an indication of a plurality of modes of operation of the faucet, including a mode when water is flowing through the spout. 21. The faucet of claim 20, wherein the logical control provides touch sensing and proximity sensing. 22. The faucet of claim 21, wherein the logical control includes: a first mode, wherein the proximity sensing is inactive;a second mode, wherein the proximity sensing is active; andthe mode indicator is configured to provide a visual indication of at least one of the first mode and the second mode. 23. The faucet of claim 22, wherein the logical control further includes a mode controller that changes the faucet between the first mode and the second mode in response to substantially simultaneous touching of the spout and the handle. 24. The faucet of claim 20, wherein the light emitting device is configured to selectively display light of different colors. 25. The faucet of claim 20, wherein the light emitting device is configured to emit a solid blue light when water is flowing. 26. The faucet of claim 20, further comprising a manual valve coupled to the handle. 27. The faucet of claim 26, wherein the manual valve is fluidly coupled in series with the electrically operable valve.
