• That seems it move forward, but it returns the undefined.

    I2C1.setup( { sda: D20, scl: D19 } );

    See here full snippet:

    >I2C1.setup( { sda: D20, scl: D19 } );
    ERROR: SDA and SCL pins must be valid, got 255 and 255

    As you may tell that I'm very new to this. This feels like I'm trying to push a wooden triangle in the circle hole without knowing what those are.

    I followed the tutorial and it worked but when it comes to me trying to move the motor, it didn't work. Any advice?

    I truly appreciate your time!
