I2C Master-Slave Arduino system to control array of steppers trying to make a system where one master Arduino makes moving 9 steppers 28BYJ-48 by 3 stepper on each slave arduino.
While all the parts on their way to me, wonder to check with professionals.
Maybe I've missed something?
Any suggestions and tips are welcome.
Thank you.
I don't quite understand the problem. A
 arduino mega would have no problem controlling 9 of these steppers alone. If you are asking about i2c protocol please be more specific about what you need help with.
