I want to ask whether i have a proper connection between, 4 servos, the arduino and its power. Because, i have tried it, but it can't move properly regarding to my command. I use XBEE wireless connection with Labview. if i use it for 2-3 servos, it runs properly , but if >4 servos, it seems that the command cannot go through all servo, it rotating but, sometimes it stuck or disobey the command i gave. is it the power problem or the circuit scheme i made?, thank you, i'm just a noob to this kind of things..
i already attached the image for circuit scheme and labview code.
any suggestion is highly appreciated. Thank you,
