Arduino focuser and rotary encoder. Help

[VincenzoRoma]

Seeking help finding a working code to use a single rotary encoder, and the built-in push button on it cycles between fast and slow modes.

I need it to avoid focusing my high magnification C8 without touching the wobbly telescope.
I found the suitable code but the button code returns the motor to its home position; i can't find anything else and i don't know arduino programming.
Thank you in advance.

Sorry, i forgot to tell my equipment:

Arduino Uno or Nano

Stepper  28BYJ-48 ULN2003 5V

rotary encoder KY-040

I don't use an encoder, but have look at MyFocerPro2 (https://sourceforge.net/projects/arduinoascomfocuserpro2diy/) It should easily do what you want, but may need a slight re-config to use the encoder...

Thanks Julian for the advice,

I already use a focuser PC controlled, I was looking for one to use manually and the one with the rotatory is better than using the buttons.

Hello,
I manipulated two separate projects found on the internet and managed to make my own automatic focuser project: rotary encoder for fine focusing and two buttons for fast forward and fast reverse.

For those interested in the code let me know
