In order to control and drive the pneumatic components in the microfluidic chips for the complicated manipulation of the fluid in the microchannels, a control system based single-chip microcomputer is introduced in this paper. This system could provide an integrated approach to control several pneumatic components in the microfluidic chips simultaneously by the circuit design and programming. The microchannels, micro valves and micropumps integrated in one chip could be controlled by the system through press keys and solenoid valves. The fluid in the microchannels is selected or driven with the actions of the micro components. The pulsatile characterization of the fluid driven by the system is also analyzed. This circuit can make it easy to control the fluid in the microfluidic chips in a simple and robust way. And it could extend to different microfluidic platforms for complicated applications.
