Figure Lengend Snippet: (1) AC-DC adapter; (2) blade fuse and connector; (3) 9-V battery; (4) toggle switch; (5) Arduino Uno; (6) Adafruit stepper shield for Arduino v2; (7) stepper motor. Red lines denote the positive line extended from the positive battery terminal, while black denotes the negative line. Green boxes and arrows denote header pin connections and blue A+/− and B+/− represent the phases of the stepper motor connected to the Adafruit stepper shield.
Article Snippet: Open in a separate window Fig. 1 ∣ Overview and detailed parts and schematics of dual-pump small-animal blood exchange device. a , Image of the dual-pump small-animal blood exchange device with denotations of the parts involved in constructing the external hardware of the pump including appropriate tubing. b , CAD image for 3D-printed hardware housing of the pump with dimensions. c , Exploded view of the dual pump illustrating the intersection of the incorporated components. d , Dual-pump electrical wiring diagram. . Electronic components for the dual-pump small-animal exchange device The pump system is controlled by an Arduino Uno microcontroller electronic board that allows for both digital and analog input and output pins that can be integrated with different circuitry and an accompanying programmable computer code through an Arduino software ( https://learn.sparkfun.com/tutorials/what-is-an-arduino ).
