hi guys
am working on a project where i need to connect 20 servo motor to a power source.The 20 control ports will be connected to Arduino. The arduino has its power source from USB.
the only servo motor properties i have are below :
stall torque : 1.8kg/cm
operating speed : .1sec/60 degrees(4.8v)
operating voltake : 4.8 v.
not sure of current rating and they are very small servos. the width n height are almost half of an avg finger length.
i tried using mobile charging adapter that has power rating 5v - 0.7A but was not sufficient enough to rotate even 4 of them.i guess the current is not enough as they got divided by 4 .i connected the servos in parallel.
I have another adaptor of 9 v - 1 amp but afraid of using as it may damage the servos.
can you pls suggest as how can i source the servos.
pls note i know only basics.
thank you.
Regards,
Sandeep
