specific stepper motor design
« on: November 17, 2011, 21:45:34 PM »
hello all

i am gathering info in making a stepper motor circuit.
i want to create a circuit that,when its powered up, will physically push a button.so i thought of a stepper motor.turning 180 degrees.stopping for 2-3 seconds and then turning another 180 degrees
has anyone done something similar?is stepper motor the best approach?

i wonder if the motor will lose accurancy in turning.
also.how can i make the motor execute the sequence only once?

thank you

hello aggelos,
your best choice is not a stepper but a servo instead. Check this out first:

How RC Servos Works

RC servos are usually powerful. Here is a project in which i used RC servo:
