a) Photo of the open source control platform designed around the Arduino prototyping board. b) Schematic detailing the working mechanism of the control platform. The Arduino provides an alternating signal that controls a motor driver that gates a high voltage source. As the motor driver opens and closes the circuit, the high voltage signal is passed to the transducer in the requisite alternating pattern. Photos of the c) sharp edge based and d) bubble based acoustofluidic devices, which are two of the acoustofluidic devices that are compatible with the platform.
