hitec servo question

Using Arduino Motors, Mechanics, Power and CNC

hi i am planning to make a robot arm that requires 180deg rotation.

ive set my eyes on hightec hs325hb servo motors

i know most standard sized servos rotate 180deg via arduino.

but when i asked the person who sells them he keeps sayin it rotates only 90deg...

i cant find the info anywhere on the net so as a last resort ive came here for help!

can hightech servos , specifically hs325hb be rotated 180?? via arduino??

also i am controlling two servos,,, is it possible to use servo.write to simultaneously control two servos?

Hi.

Googling for hs-325hb datasheet leads to this 2nd. hit: Hitec HS-325HB Servo Specifications and Reviews.
It tells you you won't have 180 degrees.

I can't tell you how accurate that site is (it doesn't seem to be related to the producer of the servo).

You cannot do 2 things simultaneously with an Arduino.
But you can do things very fast one after another so that it seems to happen at the same time.
Learn a bit about how servos are controlled, and find out whether or not it would be needed to do things simultaneously.
Keep in mind that a servo needs to overcome some momentum, leading to a delay of sorts.

Wrong, so wrong.... Most have somewhere around 120 to 150 degree motion, which
is perfectly adequate for their role in RC planes as control-surface actuators.
