I have a project of developing a control box for a discarded robotic arm. My design intends to use the Raspberry Pi to process the controller algorithms send the the appropriate signals over to the ARduino to initalize PWM modulation to be sent to the various motor controllers.
Currently considering send data to the Arduino via USB cable.
Is this the fastest way to transmit data from the Pi and Arduino??/ Is this the best way to provide communication between the boards with regards to a project as such.......
Note that the arm has 6 12V motors including the gripper motor...
