Automatic Blinds

Recommended Posts

I am looking to build a devise that will open my vertical blinds in the morning and then close these in the evening when light fades, automatically using LDR. Therefore, I want to power a geared dc motor so that it alternates its controls to rotate clockwise and counter-clockwise. Also I need to control the speed of the motor. Could someone please help me with a circuitry to do this.

If you are going to base ur operation on morning or evening (time of the day) then a RTC solution would be lot more reliable than a LDR.
