What is the resolution of rotation of hobby servos

-

i've got couple of hobby servos i'm using on project. firstly understand servo library included in arduino allows ints when writing servo itself. i'm not sure if purely limitation in software or maybe because servos cannot rotates < 1 degree. i'm new electronics forgive me being bit thick.

is possible create rotations smaller 1 degree. can see lib supports writemicroseconds, im not sure does.

any help?

have looked @ how servos constructed? little plastic gears molded millions on plastic shafts dropped molded, not machined, holes. several of them per servo drop speed of crude little electric motor thousands of rpms down reasonable speeds servo.

have looked @ how small motion 1 degree is? @ second hand on watch (assuming has hands). little space between straight noon , 1 second after 6 degrees.

now, why want use cheap hobby servo , move in less 1 degree increments?

hello ! wrote today article on blog cpu load monitoring (using gpio , leds) on raspberry's. simple (written in little shell script), think can useful (for people want learn leds stuff on r. pi) there 5 leds turning on , off regarding cpu load: - cpu < 20%: 1 led - cpu < 40%: 2 leds - cpu < 60%: 3 leds - cpu < 80%: 4 leds - cpu < 90%: 5/5 leds - cpu >= 90%: 5 leds flashing here article: written in french, can watch youtube video , download code @ bottom of article. http://www.chteuchteu.com/2012/10/26/ra ... e-au-gpio/ if find errors in code, can post comment on article. ! up code enhancements ? raspberrypi
