Arduino-Driven Multiple Liquid Dispenser
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?
