This topic relates to controlling up to 10 stepper motors, each at a time, from single Arduino (additional electronics as required) and over minimum number of wires running in parallel between all motors.
As shown in the attached schema, I am designing a blast gate control system for my workshop and need to open/close a blast gate depending on the machine I am working on. There are T’s in the dust collectors pipes so I may need to open/close more than one blast gate but this can be done in serial.
I was looking at the BOT-06640 http://www.geeetech.com/5v-4phase-5wire-stepper-motor-p-368.html stepper motor as an option but it can be any other small motor.
- Can you control more than one motor with single driver? Can it be done with some sort of relays matrix that connects the target motor to the driver?
If not possible to use one driver for multiple steppers:
2. What add-on is recommended to expand the number of pins coming out the Arduino?
3. Is it possible to place the drivers near the motors and control all of this using 2-3 wires cable?
Thanks a lot!
