Following is a simple class that start and stops spinning an object using two buttons, I hope it makes a starting point of what you are trying to achieve.

public class TestSpin : MonoBehaviour
{
    public float speed = 500f;
    public Button starter;
    public Button stopper;

    bool IsRotating = false;

    void Start()
    {

        Button btn = starter.GetComponent();
        Button butn = stopper.GetComponent();

        butn.onClick.AddListener(FidgetSpinnerStop);
        btn.onClick.AddListener(FidgetSpinnerStart);
    }

    void FidgetSpinnerStart()
    {
        IsRotating = true;
    }

    void FidgetSpinnerStop()
    {
        IsRotating = false;
    }

    void Update()
    {
        if (IsRotating)
            transform.Rotate(0, speed, 0);
    }
}
