Hi
Thank you for the other dwgs. I do not think I need to change it analog.
So what is the connection between the Pi and arduino?
Correct me if wrong
PI to Aduino
Pin 8 on pi is tx going to pin 1 on arduino is tx
Pin 9 on pi is rx going to pin 2 on arduino is rx
5v and ground to arduino from pi
Arduino to motor controller MD10c R3 (it has three pins of input ground, PWM, DIR
Pin D 9 on arduino to pwm on controller
Ground to ground
Then there is DIR what goes to that?
Thank you
Or should I be getting the pololu vhn5019 like the newer dwg you linked? If so what is the usb link it has?
