testing $50 robot servos

[goatfish]

is there a way to test that the servos work when you first receive them? the hitec hs-322 hd requires 4.8-6.0 volts

servos need a pulse to operate

so you could either use a microcontroller to give that pulse or use a 555 timer chip to give the pulse

I would go with microcontroller if you have a programmer for it

do you know the code to send a pulse to the servo?

i have only just received the servo today,
is the microcontroller the brains for the $50 robot
i would need to know how to connect the servo to the 555
and i know nothing about robot code apart from it has funny symbols lol

here is a link about it , if its not enough search google for "555 timer with servo"

http://hades.mech.northwestern.edu/wiki/index.php/555_Servo_Circuit

A typical servo needs a pulse of 1.0 ms to go all the way to the left, 1.5 ms to center , and 2.0 ms to all the way to the right.

microcontroller is the brains for the 50 dollar robot

learn robot code , because the 555 timer circuit may be a bit too complicated for you
