Arduino-Driven Multiple Liquid Dispenser Answered

Hi all!

I'm looking to find an Instructable for an Arduino-driven multiple liquid dispenser.  So for example, let's say I wanted to test 100 different combinations out of 20+ liquids (juices?).  I want to be able to push a button, and that dispenses x-liquid of a-volume, and then I push another button that dispenses y-liquid of b-volume using an electric dosing/metering pump into a main mixing reservoir.

Something like the Bartendro, except on a semi-precised millileter scale?

Ah,...dispense..mix..sample..drink...repeat...the scientific method.


Hi Bryan,

Have you found anything yet? I want to build a "dispenser" that issues approx one new drop of liquid per second.. not a stream, but individual drops. Any ideas? Drop size can be relative to the viscocity of the liquid which allows a cruder design I think.

Thanks, Bill

try to look at peristaltic pumps, they are used for those medical IV devices to give accurate dose or flow.
