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!
