No, I dont have the photo cell yet, what would be the best kind to use?? This is how I would like for this to work... At daylight the photo cell will activate a 6VDC or 12VDC motor to run for ten seconds, now if I can use a DIP switch to have different configurations of cycle times for like in between 5 and 20 seconds that would be great too, but no more than 20 seconds.. and sometime before dark, when the photocell acivates agian the DC motor would run for the set amout of time.... I really don't have to use a photocell for this, I just thought that it would be the easiest and cheapest way. If I could use a clock to trigger the this that way I could have more than just two times that the motor would be activated.. I know that there is alot of diffrent ways to build this configurtion, but I would like to build one myself for less than $25 I can get this already made for that price... I hope that I am explaining myself well enough... If you have anyother questions just ask.........Thanks
