Controlling of CKD MEVT Valve ( Analog valve) using Arduino Mega

The project aims to develop a pneumatic system control box controlled by Arduino Mega. CKD MEVT Valve with 4 channels will be used each channel has its knob ( potentiometer ) to control the airflow, where the knobs function is the controlling of the flow rate of air and speed. Each channel also has its off/on button and there is an emergency button to reset the system.
