Fig. 3 — An Arduino-based electronic control scheme for flow control is shown. The yellow blocks represent the intermediate electronic components that interface with the electronics of the flow control components, voltage regulators, and power resources. The blue blocks represent the electronics of the flow control components. The green blocks represent the pressure control components. The RC filters convert the pulse-width modulated output signal from Arduino to analog setpoints for the controllers
