Hello, I want to control a single stepper motor with a rotary encoder. I have all the parts required, I've successfully downloaded basic programs and made the stepper rotate using https://www.arduino.cc/en/Tutorial/LibraryExamples/StepperOneRevolution
I have just checked out the rotary encoder using a program I found working via the uln2003 driver and 28byj-48 5v stepper.
From that program I saw the Uno was taking the encoder signal on A4 and A5
I've checked and these correspond with SDA and SCL pins on top of the shield
I can also pick up 5v and gnd from the top of the shield for everything required for the encoder
I feel Ive got everything I need to start writing code but often after changing something fairly simple the program no longer works.
Appreciate any constructive pointers
