i had a servo whit a clicking sound in it.there where more byers who has this sound.
so i thought it was normal,till today when i connected all in the robot.
power up the robi and there was smoke,lucky i had connected the on/off swits.
the damage hopefully is only wires.
now i have to wait a hole week for a wire from less then 1 gram 7 cm long *tired* *mad*
so never use a servo that makes any not normal sound.
Upgrade to ARC Pro
Your robot can be more than a simple automated machine with the power of ARC Pro!
its the desig ,the way you have to close the servo.
i hope its only two wires.
