Hello,
This time I need to find a circuit that will generate a pwm output signal that is able to drive a servo motor. The output signal needs to ve controlled from a 0-5v input. What I want is that that the servo will adjust its position depending on the input voltage to the circuit.
I want to control a variable geometry turbo and a servo has it's own positioning control so I just need to tell it where it needs to be. I'm using a pressure sensor that goes from 0 to 30 psi and the voltage output is from 0 to 5v.
Anyone has a good idea or a circuit schematic with parts list to accomplish this? Most 555 circuits that I find out there involve moving a variable potentiometer to adjust the servos position.
