microcontroller - Proportional Solenoid Valve + Arduino


I am thinking of buying a proportional solenoid (PVQ31) valve for a project. I thought of using Arduino to drive this valve but the issue is - this valve needs a range of current supply (0-165mA for 24V or 0 - 330 mA for 12V) for flow control. How can I have current control using Arduino? I thought of using digital pots but they operate at 5V only.


Please suggest a solution.


Thanks.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
