Hi, Im thinking of creating a robotic arm as a project, the only problem is im not sure how I should approach it. I was wondering if it was possible to stack a host shield on an arduino UNO and than to stack an Adafruit 16-channel PWM/Servo Shield on top of the existing usb shield. so ultimately creating a 3 layer control board system. The reason for the USB shield is dor Ps3 blutooth control and the Adafruit for servo control.
Im very open to suggestion and if u know of a way for me to control multiple servos on one arduino while control them via a ps3 controller please let me know.
