I’d like to make the mCar project, but don’t want to purchase the Me Orion/shield for an arduino. I have everything needed, including the stepper motors, stepper motor drivers, and an Arduino Uno.
However, the car_robot firmware doesn’t give pin numbers- instead, it has Port1 and Port2 listed under the included pins. How do these correlate to the arduino uno without having a shield? Which pins do I use on the Arduino?
From what I have found, the connection that the first driver would connect to on the Orion consists of 10, 11, GND, V-M,SDA, and SCL. What are the last three on an arduino uno?
Same goes for the second, except 9 and 3 is listed.
And for the lifting servo, is it really just pin2?
Thanks!
