Servo powered peristaltic pump controlled by Arduino

This instructable shows you how to make a pump using a servo motor and an Arduino Uno to transfer small amounts of liquids. The pump is a peristaltic pump which consists mainly of a motor, flexible tubing and a circular pump casing. Two rollers attached to a turning rotor press the flexible tube to the circular pump casing wall. As the rotor turns, the part of the tube under compression is pinched closed th ...
