摘要： The automatic window blind system provides gear driven window blind control. A solar power with back up battery provides energy to operate the window blinds and a light emitting diode strip that changes light colors depending upon daylight and night conditions. A plurality of toothed rack drives is driven by and drives rack gears in ensuring a positive operation of window blind hooks in pivoting window blinds that snap into the window blind hooks. A printed wiring board assembly controls functions and is accompanied by a rack sensor that cooperates with an optical sensor. The optical sensor and the rack sensor automatically position window blinds based upon light intensity.
