    Hi,

    Are you using some kind of level shifter between the Uno and the bricklet? This is required as the Uno (and all other AVR based Arduinos) have a logic level of 5V, but the bricklets only work with 3.3V. Some Unos seem to understand the 3.3V high level as a 5V high level, but some don't.

    The error code -10 indicates that the bindings can't find the bricklet (see errors.h), so you either have the logic level problem from above, or you use the wrong UID. The bindings will print all found devices to the serial console when tf_hal_arduino_init runs. You can connect to the serial console (maybe add a delay(5000) at the top of your setup-function, so you don't miss the output) and check if the bindings see the bricklet under another UID.

    Hello, I'm actually not using any level shifter I figured that 3.3 would be enough for the arduino to get a HIGH level, I'll try with a level shifter,

    Regarding the UID, how can I get the UID of my bricklet?

    Thanks for your support,

     

    Hallo, ich benutze eigentlich keinen Level Shifter. Ich dachte mir, dass 3.3 ausreichen würde, damit der Arduino einen HIGH Level erreicht. Ich werde es mit einem Level Shifter versuchen.

    Wie kann ich die UID meines Bricklets in Bezug auf die UID ermitteln?

    Danke für deine Unterstützung,
