Valve Pressure/Flow Testing
The humble beginnings of an automated bartender. When complete, it will be a system of valves controlled through a LabJack that can dispense your favorite cocktail at the press of a button. The test scenario above involves a 24V DC solenoid valve, a pressure tank filled with air to 20psi, a 2-litre bottle of Dr. Pepper, and some 1/4" nylon tubing. Next phase: Assemble a circuit to interface a LabJack with the solenoids.
