    Hi Lucko,

    please share with us your test setup wiring – a drawing or photo will be great!

    Thanks,

    Lukas

    Hello Antonio,

    I assume that Marco means to configure the pins 20 and 21 as digital outputs and try to trigger them to LOW and HIGH and measure the output voltage.

    In addition – may I ask you to share the I2C detector sketch you use?

    Thanks,

    Lukas

    Hello,

    each digital/analog input already has internal pull-down resistor as a part of the voltage divisor inside. The behaviour you describe seems to be caused by really high noise on the line. Nevertheless I will try to investigate it more.

    Thanks,

    Lukas
