I have an ATTiny24 IC cycling its output pins in order to drive a number of stepper motors at a specific speed. A single ATTiny24 drives drives 6 ULN2003's which in turn drive a 28BYJ stepper motor each. The ATTiny's only job is cycling its outputs to drive the ULN2003's.
Another programmable IC, and ESP32, needs the ability to turn each of these of the stepper motors on/off.
This image describes the ATTiny24--UNL2003--Stepper combination:
I request advice regarding how the ESP32, using one GPIO pin could turn one stepper motor on/off without interrupting the ATTiny24 or other motors.
Everything runs from the same 5V source.
A simple schematic would be greatly appreciated.
