servo motor source diferrent source from pic? or not?

[jAnzY]

good day...
hhingi po ako ulit ng tulong..

ung source po b ng servo motor hiwalay sa source ng pic?
kc po nung tnry nmn n mgksma ayw po gmna ung servo ng tama lalo n pgpnipindot ung switch,,,
pero nung hiniwalay nmn gmgana na po xa ng maayos pero umiinit ung servo,, normal lng po ba un?

salamat po sa mga mgrrply,,,

i would suggest na ihiwalay mo lang nang regulator. and get a bigger power source. adding a filter caps will also help a lot.

medyo noisy din kasi yung motors nang hobby servo.

[jAnzY]

salamat po sa reply.

what do you mean na ihiwalay ng regulator at filter caps?
hnd ko po gaanu naintndhan,

[jAnzY]

battery n 6 volts lng po gmit nmn

[Cross Talk]

battery n 6 volts lng po gmit nmn

so you mean walang regulator circuit mo? buti hindi na sisira yung mcu mo... since 5.5 V lang max nyan.. anyways

dalawa needed mo isa sa servo, isa sa mcu...

[jAnzY]

sa ngaun po usb cord lng gmit nmn den connect s pc,, ang output kc nun 5volts,,
dont wory po hnd pa nmn kinokonek ung 6v battery sa mcu,,

kktry q lng po kniknina lng ung separate na source,, ok nmn po,,
kc nung first try uminit ung servo,,
d nmn po cgro un mccra?

GACK!

right now stop using the usb's 5 volt since 500mA lang kaya nyan! baka masunog yung fuse nya. malas pa kung hindi polyfuse! a small servo typically has a 800+ mA of stall current.

waaaaaaaaaaaaaa,,,,
cge po not gonna use that again,,

eh panu po ung sa charger,, gmgmit dn ako nun eh,, sa charger nangggaling ung source,,?

Charger? as in for cellphone? typically nasa 500mA din yang mga yan. pero wala naman masama kung ayan gagamitin mo. a 1000mA adapter sa local hardware will do. (don't forget to put a 7805 regulator)

[jAnzY]

yup charger sa mga celphone and mp3's,,,
db po ang output voltage nun nsa 5volts,, 3.7volts nmn kc ung battery ng celphones..
la nmn po b mgging effect qng un ggmitin ko? db po sb mo 500mA lng un,,
ung sa usb nkksama,,,

ung sa regulator po,, pwd po ba un sa battery n 6v? pra output nya 5 volts?

[LTSGü]

ask lang kung okay lang po ba hindi regulated yung supply ng mga servo??

sir martin ung 9v na adaptor na may 1000mA po ba un? pra gumamit ng regulator?

[insomartin]

rule of thumb is gumamit nang regulator when working with hobby servos. 7805 will do.

ok po. khet po 5v lng or 6v ung source? regulator pdn?

yung mga ibang servos is mcu din ang nasa loob. kya better din na may regulator. ok lang kung cheap yung servo motors. a "15 peso" add on will not hurt naman right? considering na 500++ pesos isang servos

[jAnzY]

cge po salamat,,

[insomartin]

kung 24 servos every foot (3 segments) mag lagay ka nang regulator.

[jAnzY]

cge  po ggwin ko un,,

sir pero may nabasa ako about sa regular na dapat pag gagamit nun, ung voltage in is 7V-36V taz ung out nya 5v.

^ correct. pwede kayo maghanap ng LDO (Low Dropout) regulator para kahit 5V 'yung input, almost 5V pa rin ang output. or you can design the regulators yourselves. medyo madali lang 'yun, NPN, PNP, TL431, at ilang passive components lang ang kailangan.
