I'm working on a project where I need to use a photocell to activate a motor. What I've done so far is place a photocell, that I bought from Radio Shack, in line with a 9 volt battery and a small fan. Originally the fan ran off of two AA batteries, but it also runs fine if you hook up the 9 volt battery to it. My problem is the fan WILL NOT work once the photocell is plaqced in line. I've checked the p/c and it appears to work correctly. Does anyone have any simple ideas on what I could do to make the fan work with the photocell???
