    Hello Labo,

    to IN0 and IN1 – please note that these inputs have external pull-down inside the CONTROLLINO.

    Do not use INPUT_PULLUP and connect it IN0-BTN-SUPPLY and it will work fine.

    To the pinout diagram – grey numbers are numbers of physical pins at the microcontroller. Arduino pin numbers are blue.

    To the digital inputs – the same situation like with the IN0 and IN1. Use already existing pull-downs inside CONTROLLINO and switch it to supply voltage. Or, use additional external pull-ups. Check our FAQ No.12 for more details about the external pull-up values.

    Good luck with your project!
