1. A liquid dispenser for dispensing a predetermined quantity of said liquid, comprising: a liquid reservoir having an openable refill lid that provides a substantially horizontal cover over said liquid reservoir; anda dispensing chamber assembly located substantially below, and in fluid contact with said liquid reservoir via a tube;wherein said dispensing chamber assembly comprises: an inner dispensing chamber comprising a hollow cylinder having a first closed end and a second open end, an inner inlet orifice located on a wall of said hollow cylinder and an inner outlet orifice located on a wall of said hollow cylinder;an outer dispensing chamber comprising a hollow cylinder sized and shaped to rotatably fit over said inner dispensing chamber, having a first closed end and a second open end, an outer inlet orifice located on a wall of said hollow cylinder and an outer outlet orifice located on a wall of said hollow cylinder;and a singular fluid sealing element located between said inner dispensing chamber and said outer dispensing chamber;said inner dispensing chamber being located within said outer dispensing chamber with said second open end of said inner dispensing chamber being positioned proximate to said closed end of the outer dispensing chamber; saidinner dispensing chamber being rotatably adjustable between a first position and a second position; said first position comprising said inner inlet orifice and said outer inlet orifice being sufficiently aligned to allow fluid to flow, under gravity, from outside said outer dispensing chamber into said hollow cylinder of said inner dispensing chamber, and said inner outlet orifice being sufficiently out of alignment with said outer outlet orifice that substantially no fluid flows through either of said outlet orifices;said second position comprising said inner outlet orifice and said outer outlet orifice being sufficiently aligned to allow fluid to flow under gravity from said hollow cylinder of said inner dispensing chamber, to outside of said outer dispensing chamber, and said inner inlet orifice being sufficiently out of alignment with said outer inlet orifice that substantially no fluid flows through either of said inlet orifices,and said singular fluid sealing element having two holes aligned with the inlet orifice and the outlet orifice of the inner dispensing chamber, said fluid sealing element rotating with the inner dispensing chamber. 2. The liquid dispenser of claim 1 further comprising a lower portion having a lower portion housing; wherein the lower portion housing encases the dispensing chamber assembly. 3. The liquid dispenser of claim 1 further comprising a lock, said lock locking the refill lid, preventing access to the liquid reservoir. 4. The liquid dispenser of claim 1 wherein said inner inlet orifice and said inner outlet orifice are offset from each other by an angle in a range of 110 degrees to 160 degrees. 5. The liquid dispenser of claim 1 wherein said inner inlet orifice and said inner outlet orifice are offset from each other by an angle of substantially 135 degrees, while said outer inlet orifice and said outer outlet orifice are offset by an angle by and angle of substantially 180 degrees. 6. The liquid dispenser of claim 1 wherein activating a rotary solenoid having a cam or a radial armature changes the orientation of said inner dispensing chamber with respect to said outer dispensing chamber from said first position to said second position. 7. The liquid dispenser of claim 2, further comprising: a rear base, wherein the lower portion housing is mounted on the rear base, and the rear base is mounted on a vertical surface. 8. The liquid dispenser of claim 2, further comprising: an optical receiver, the optical receiver detects movements under the lower portion housing and triggers a transition from the first position to the second position. 9. The liquid dispenser of claim 8, wherein the optical receiver attaches to the outer dispenser chamber. 10. The liquid dispenser of claim 1, further comprising a motor assembly, the motor assembly controls transition from the first position to the second position. 11. The liquid dispenser of claim 10, wherein the motor assembly is controlled by a processor board. 12. The liquid dispenser of claim 10, further comprising: a lever connected to the motor assembly, wherein the lever extends through lever holes on the lower portion housing, andpushing the lever switches the chamber assembly from the first position to the second position.
