This is an amazing project! love that it has a phone UI and OLED support!
I see a lot of DIY watch winders use small stepper motors like the 28BYJ-48 unipolar stepper motor with the ULN2003 motor driver, it would be nice if you could enable the Winderoo code to work with these motors as well since they're so cheap and accessible. These fancy 3D printable gyro winders also use the same motors.
I did attempt to modify the code as suggested by an ESP32 forum user, but I'm an ultra noob and I could not wrap my head around switching the PWM motor control code to a stepper motor one.
