Hi friends
i have bought a 12v dc motor .the motor gives or subtends an angle of 90 degrees which is not suitable for my application. I want the motor to subtend an angle of not more than 60 degrees and stop without getting to90 degrees.
Friends,how do i go about this successfully?

I am going to use a timer so that the motor moves from zero degrees to 60 degrees and stay there for an hour.Then return to zero degrees for an hour.Then the cycle continues indefinitely !How do i make the motor not go beyond 90 degrees on each occasion?
or use a stepper, more accurate. You may have to use a micro-controller, the same micro-controller could also keep track of the time and reverse the motion after an hour.
Dear Arunb
thanks for the advice.I am a novice when it comes to micro-controllers.Can you point out one particular micro controller on the net which can do this job as effeciently as effeciently as possible.That is a micro-controller which could also keep track of the time and reverse the motion after an hour.

africa needs technology not aid!I need old books ,brochures etc to improve my knowledge on micro controllers,limit switches and automation in general.If any body can send me books in any of these areas i would be very grateful.My adress is:

Hi Mike
What accessories do i need to use wit the limit switch for it work 100%?Do i need a install a timer or counter together with the limit switch to make it turn once evry hour?

nope... all he needs it to use a step/direction stepper controller and a little logic... a counter to change the direction input when it steps to the end of the travel

Do you have a printer? The information you're looking for can usually be found on the internet. I've literally printed my own books off the 'net, sometimes by using information from several sites.
