Secureit Posted May 19, 2014 Report Share Posted May 19, 2014 Hi,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. Quote Link to comment Share on other sites More sharing options...
Guest enggricha Posted May 22, 2014 Report Share Posted May 22, 2014 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. Quote Link to comment Share on other sites More sharing options...
