I Want create a blind opener using the Arduino Uno. I want to use a photo cell and a servo. It would be nice if when the photocell recieves light, the servo would spin 360 degrees for 3 seconds.
Thx
360 degrees for 3 seconds would be dependent on a precise speed. Timing is a bad way to do this. It's better to use a limit switch. And do you also want the circuit/program to close the blinds?
But the real point - you didn't actually ask a question.
Servos generally don't spin 360° - maybe a DC motor instead?
I want the continuous rotation servo to close the blinds when it is dark and open them when it is morning.
help-me-please:

Still no question. Are you asking for the code to do it?
i am asking for the code and the breadboard diagram
I would like the motir to do a certain ammount of 360 degree rotations, which I can change for my own needs.
You'll need to write your own code, and do a little research to learn how to power and connect a servo. Then if you strike problems along the way, post your questions and we will help you.
For starters, check out the "Servo" library that's included with the IDE.
Or, if you really want someone to do it all for you, you could ask to have this thread moved to the "Gigs and Collaborations" section of the forums, but if you do that, be prepared to pay someone to do the work.
And with a continuous-rotation servo, there is no way to know how many revolutions it has done unless you add an encoder of one sort or another. You can set speed and direction, but not the number of rotations.
thx

There's another one in Gigs and Collaboration, then.

What type of blind are you trying to operate. I've made a blind operator in the past that operated the slats on a Venetian type blind. A six turn sail winch servo probably can rotate the blind wand thru its full operating range. Use the forum search box in the upper right to find previous discussions concerning blind operation.
