Hi! I'm new to Arduino and I'm trying to build a hexapod using 18x sg90 servos because they are very cheap. For power supply, I'm thinking about using 8x AA 1.5V batteries. 4 are in series and this series is connected in parallel to another series of 4 so that the servos receive more current. I'm using Arduino Mega Board.
Should i connect the Mega to the same supply with the servos or use external?
Are 18x sg90 servos strong enough to bear the weight of Mega and the two battery packs?
I appreciate any help.
Thank you.
I'm thinking about buying Lipo battery and voltage controller. Any recommandations?
