centering servomotor using 16F84A

[saturnX]

hi Acetronics,

thanks for the reply, i will try your suggestion later on as i was playing around with the schematics last night and managed to get it to work. I incorporated a voltage regulator to regulate the power supply to the pic and the motor and guess what it worked. But i never thought of your way Acetronics and will try it later. Thanks again...

alain, hoping you do read this thread still. i was just reading through wat you posted and i was just wondering, is it necessary to have a resistor between the IC and the servo? I am not that good in electronics yet and slowly learning so your help is much appreciated.

Hi, Saturnix

Resistor is not compulsory ... but protects the pic from little things : bad cord connexion and servo input capacitor's discharge in the pic's pin ...

consider a servo input is often a 1 to 4.7µF cap in series with the amplifier ... so plugging the servo when power is on gives strange things ( reason of the LOW command before PULSOUT ...)
