Help - LDR controlled dc motor I am starting on a project for uni , the product is a device that controls the curtains of a window depending on the light coming from outside using an ldr and DC motor .
I would like to know how/if it's possible to have the have the DC motor operate in reverse.
Eg. If it gets dark outside the curtains open and if it's bright outside the curtains open up.

I don't expect a full explanation but any tips or notes will be highly appreciated :).

Thanks
