setup is a classic 16x2 LCD with i2c module run off a Raspberry Pico and have failed at understanding how to set the gpio 4 and 5 as SDC and SCL using the Arduino ide.
every example and video I have found is in python and they set a value to the pins but I have no idea what function it is for Arduino ide and the syntax for that.
secondly the 3.3v will be enough to set the SDC and SCL lines? I can power the display from the 5v
to have a bright display but do the SDC and SCL have to be logic converted to 5v for the lcd?
