I need to control a pressure control solenoid, basically the solenoid is controlled by using current. The current needs to be between 0 - 1.1 amps @ 4-5V (need the ability to control the current via a microcontroller in small current steps). Was thinking of using a PIC but don't know how to design the circuit? Assume use an analog output of a microcontroller to controll a transistor but it would need some kind of current sensing ability? Can anyone help or point me in the right direction? Thanks.
