Motor triggered by a vibration sensor Answered

Hi, my project consists of a vibration sensor that, when enabled, will trigger a motor which will function for a certain amount of time, then stop, and stay in this position as long as the sensor is detecting vibrations.
When the vibrations stop, I need the motor to reverse polarity and function in the opposite direction,for the same amount of time as before then stop, and repeat...
I'm a first year electrical engineer so please consider me a rookie in this field.
If someone could provide me with a suitable electrical circuit, with names and values for the part, i think i might be able to draw the corresponding board.
Thanks
