Servo control newbie help

[jascore]

Hi there.
I'm doing a project that requires a servo going from 0 deg to 180 deg to 0 deg only once every X hour.

I considered using a 4060b for the 0-24 hour timer and a 555 to controll the servo movement.

when pin 3 on the 4060b triggers pin 2 on the 555 the servo makes one cycle.

i do have a diagram for the 4060b timer and one for the 555 but i cant seem to make the servo do just one cycle.

i considerd using a pic to do the job but i have no experience in programing it and dont have a diagram

hope you can help me
thanks

You could use a one-shot (monostable multivibrator) to make it do only once cycle each time and input goes from low to high.

But I would be interested in knowing how you would make the servo sweep from 0 to 180 and back with a single 555 timer?

p.s. I would use a PIC. It is trivial if you happen to be familiar with them. If you ever want to learn them, this might be the time!

i found this diagram and as i understand it it will make that sweep.
my plan was to have another timer based on the 4060 to control a relay that would power on the servo controller but there's to many variables since the servo controller will continue to swipe as long as the controller has power and therefore i figured that the 4060 would have to be timed to sync one swipe. but again I'm new to this so maybe I should just try it with a pic instead and i do know how to program but only c++ i don't know if thac is of any use

You understand it wrong then. That circuit will set the servo position to any angle by turning the potentiometer. It does not sweep from min to max. I don't think you can do that with a single 555.
