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.

Things to address following commit: cd794ce

• Track down ESP32 hard crashes
• No continuous stepper movement
• Stepper appears to be getting hot when micro steps set to 400 with 'default' microsecond interval
• Indicated rotation is the inverse of what the motor rotates

Hey, 1st of all thanks for your hard work.
I have the same situation here.
Do you have an idea when the Winderoo will be compatible with [28BYJ-48 unipolar stepper motor with the ULN2003 motor driver?
If you need any help testing software I would like to help.

KR,

Tulio
