I am looking on information to control a hydraulic solenoid valve used as a flow control valve by using PWM on the solenoid. I am trying to control a machine by skid steer, and will use the flow control to provide some trim control on slopes to cause it to go in a straight line. I am trying to develop a method to control it by radio control. there are a lot of cheap radio transmitters and receiver out there, but I do not know where to get started. I have been told to incorporate a hand held computer to program the PWM function for joystick controls, and some just say I need a microcontroller.
Is anyone interested in giving me some help. I know you guys have done a lot of this.
I am back after quite a while away from metalworking. Cecil Bearden Oklahoma
