Is there an easy way to run multiple voids at the same time on an arduino uno? preferrably without aditional libraries, but I cannot flash AVR code to it (must be through IDE). I do NEED to run the processes at the same time, no they do not share pins or variables, and the timing does not need to be precise. I am trying to run two steppers at the same time, but different speeds, but the big catch is that I don't have "smart" drivers, just a 2003 and 293, so they each require a separate void to move, and they cannot be run simultaneously without running both voids at the same time. Basically, I'm NOT looking for an alternative, just a way to run two voids at the same time (or switching back and forth very quickly without being affected by "delay();".
