I have seen many post on this site for controlling stepper motor with arduino. And arduino is pretty good at it if provide with good shield/Driver. My query is How can is use to arduino control more than 2 stepper motors i.e(64 stepper motor). It seems to be a huge project for me. Each motor will move at same speed but won't have same steps. More like MIT inForm
For now we are just making a prototype. I have attached the internal structure of or device where we will be using full stepping mode and only 2 pins for controlling Stepper motor as rest of the 2 pins are just complement of first 2 pins
a b a' b' 1 0 0 1 1 1 0 0 0 1 1 0 0 0 1 1
our basic theory/logic is arduino will generate 2 pulse of each motor pass it to serial to parallel converter and this will further send the pulse to PIC that will generate rest of the 2 pulse and pass it to stepper motor. Each pin on arduino will generate pulse for 4 stepper motor i.e. 8 bit per pin. I will be using 28BYJ-48 stepper and ULN2003 having configuration of stepper motor as 64:1 ratio the thing is at what rate I need to send 128 bits(8 words) of data from arduino to shift register. so the motor should run at decent speed So any one can help us to achieve this and guide us with the project. All reviews are welcome.
