  Microfluidics allows one to manipulate small quantities of fluids, using channel dimensions of several micrometers. At CEA / LIONS, microfluidic chips are used to produce calibrated complex microdrops. This technique requires only a small volume of chemicals, but requires the use a number of accurate electronic equipment such as motorized syringes, valve and pressure sensors, video cameras with fast frame rate, coupled to microscopes. We use the TANGO control system for all heterogeneous equipment in microfluidics experiments and video acquisition. We have developed a set of tools that allow us to perform the image acquisition, allows shape detection of droplets, whose size, number, and speed can be determined, almost in real time. Using TANGO, we are able to provide feedback to actuators, in order to adjust the microfabrication parameters and time droplet formation.
