Can i add a display to that rasberry pi or do i need to use an other rasberry pi

Can the Encoder Module with button be used on Pi 3 or 4?

Hi mine is not doing anything at all. Nothing is being printed. It is not a module so i did change it to have the pull_up.

thank you so much for the video...i am completely new to all this but managed to get it to work!!...thank you. One question, if i want to wire up 5 encoders, do i simply use 5 example codes for each encoder or is there another way that is easier? If its the 5 different files, do i save them all and maybe name each one encoder_1, encoder_2 etc? Thank you so much and im honestly sorry for the potentiallystupid qstion.

Hi, Thank you for the information an this Rotary encoder library for the Pico with Thonny. But I do have a question; does this library use interrupts in the background? This was a stumbling point for my efforts in using a rotary encoder without using constant IO polling (very inefficient) Bye
