I want to use two rotary encoders in my project. please, can someone tell me what did ı do wrong?
RotaryEncoderInterrrupts_2S_.ino (3.82 KB)
ı can't read any value from the LCD screen.
Use code tags (i.e., the "<" and "/>") to present you code in all posting on these Forums. Just click on symbols in the edit block and place your source code between the tags:

Many readers here don't like to open files with unknown content even if they end in INO. Also, the code tags properly display your code even if control characters are present, plus it will use less real estate on the screen.
