I am building a building a machine that uses smallish vibrating motors. In order to overcome inertia, when they are still, a higher voltage must be applied than would be required to run them at low speed. If the voltage applied is low and the motors are not spinning, one can push the motor manually and it will begin to spin slowly. The slow spin is desired at that point. The problem is overcoming the initial inertia. I want to provide a temporary, brief pulse of higher voltage and then go quickly to letting the motor voltage be determined by an input. The input signal will vary and when it is below a certain point, output should be held to zero. However when the input signal crosses a threshold, the output should be high briefly to overcome inertia and then have output and input match until the input drops below the threshold again.
I have set up an illustration to describe the desired behavior. Please keep in mind that I am having trouble getting the brief high voltage timer to reset.
