haleemul said:Just wondering if anyone can explain me what are stepper motors and servo motors?
what is the difference between the two? and if i were building a hexapod robot which motor would be better suited?

Most servos need 1-2ms pulse every 18ms. You can get off shelf controllers, but not the easiest thing to control from a microprocessor, cos they are effectively analogue, but everything is possible.
Alex_rcpilot said:By the way,I have a question too:if the signal I give to a servo is somehow incorrect and it greatly exceeds the limit of 1~2ms' pulse width,will it cause damage to the servo circuit?
Thanks for your reply.I better be more careful while debuging my programs :lol: .Nigel Goodwin said:I don't really know, but it is common practice to get more movement out of them by extending the pulse limits - the potentiometer inside can only turn 270 degrees though, if you try and exceed that it could break the pot, there's certainly enough power to do so - and I think it's unlikely that servos have protection against it.
