1. A window blind with actuator, comprising:

  • a horizontal window blind having slats, a head rail defining a long dimension, and a rod rotatably mounted in the head rail parallel to the long dimension, the rod defining an open position and a closed position;

    a sensor for detecting a light signal and generating a control signal in response thereto;

    a coupling engaged with the rod for rotating the rod;

    a reversible electric direct current (dc) motor operably engaged with the coupling to move the coupling;

    a dc battery electrically connected to the motor; and

    an electronic circuit electrically connected to the light sensor and the battery for processing the control signal from the light sensor to energize the motor to rotate the rod toward the open and closed positions, thereby rotating the slats.
