KY-023 XY Joystick Module Questions

Hello,

I have some questions about the KY-023 XY Joystick module.

  • The joystick has an integrated pushbutton, so do I need to place a pull-down resistor and where ?
    (In all the tutorials I saw on the internet, no-one added a pull-down resistor)
  • What is the R5 silkscreen label ?

Most probably everybody uses mode INPUT_PULLUP.

Some yes but not all,
Ok I think I understood,
If the switch pin is directly linked to an arduino input, I have to set the pin mode to INPUT_PULLUP and then I do not need a resistor.
Thank you :slight_smile:
