Probably a stepper motor or a servo
Quote from: jerseyguy1996 on Oct 19, 2012, 05:28 pmProbably a stepper motor or a servothis for example ? https://www.sparkfun.com/products/9065 and it needs 1 pin to control its direction ??thanks
If they are really light, large servomotors like these should work: http://goo.gl/DHvUT They have 7 inch-pounds of torque. Test to see what forces you really have...
Yes they will be very light , so a servo like this will work ! thanks ! how many pins does it needs ? (i hope 1 , i hope 1 , i hope 1.... etc..)
Since a servo is 0..180 degrees, I would recommend makng 90 degrees the '0' point, and then you can go from -90 to +90 from that point, by adding 90.
