Flow Rate and Volume Control of Fluid Based on Arduino for Synthesis of Silver Nanowires

In this study, we have successfully developed a flow rate and volume control system based on Arduino. This system consists of a container containing liquid, dc motor, keypad, and Arduino UNO that serves as a controller. The principle of this system is to control pulse width modulation (PWM) and delay time of dc motor using Arduino. This fluid flow and volume rate control system aims to control how much the fluid volume enters a chamber for mixing the solution. This system has an accuracy rate of 0.5 ml and has a measurement range of up to 100 ml for one process. For forward, the system will be applied to the medical as a substitute for syringe pump and research laboratory for controlling the manufacture of solutions on the synthesis of nanomaterials, especially silver nanowires.
