Abstract
The present invention advantageously provides methods for manually and/or remotely controlling a motorized roller shade that includes a shade attached to a shade tube, a DC gear motor disposed within the shade tube and a microcontroller. One method includes detecting a manual movement of the shade using a sensor, determining a displacement associated with the manual movement, and, if the displacement is less than a maximum displacement, moving the shade to a different position by energizing the DC gear motor to rotate the shade tube. Another method includes receiving a command from a remote control, and moving the shade to a position associated with the command by energizing the DC gear motor to rotate the shade tube.
