I want to control:
2 DC Motors
2 Stepper Motors(5 Phases each)
The Problem: Arduino Motor shield can only handle 2 DCs and one stepper.
What I think should work: Using Pins A0-A3, Servo pins, Digital Pin2 or RX and TX pins to control the second stepper.(A4 and A5 are used by the I2C protocol to communicate with RaPi)
So, is it possible? Are there other, simpler ways to do so?
In case it is not possible: I would also connect the stepper to my RaPi if it is possible.
I would be glad if somebody helped.
5 phase steppers? Really? You're going to have to find some 5-phase stepper drivers then aren't you??
Perhaps you should give full details of the motors? (even better explain what you actually want to do,
5-phase steppers seem expensive and exotic to me - why 5-phase?)
A serial controlled stepper driver will be pretty rare. I2C control is much more common. Stack an Adafruit motor shield for the second stepper and it can share the I2C bus with the Pi.
What do you mean by drivers? I uploaded a picture from a device i got when i ordered my stepper motors.
And the steppers wern't that expensive, it was 7 Euros each.
The thing what i want do do:
I am going to build a robot that is able to drive, therefore I need two DC Motors.
The stepper motors are used to rotate a camera vertically and horizontally. I want to be able to track objects with it. I want it to do it with the parts avaiable(those I listed), because I have already spent more money than I wanted on this project.
I already stacked a motor shield and am using R2C. The only problem is that the second stepper doesn't seem to have anymore pins avaiable. Or am I missing the point?
