power arduino and servo with the same battery

-

i have arduino controlling servo,  each 1 has own battery , works fine. 

i power both same battery when try  servo makes arduino restart.  there way avoid this?

yes lots of power supply decoupling on supply of motor. connect motor's supply through inductor , put 0.1 ceramic capacitor ground each side of inductor. put big capacitors in parallel start of 100uf might have go bigger.
