I've connected VCC + GND and SCL to analog pin 5 and SDA to 4.
Another project used this setting for a i2c-connection
But I can't see if these are the right pins! How can I figure that out? Anywhere in the library?
When I upload Hello-word the display glows but no characters are shown
I was not sure if the resistor I used has orange or brown mulitplcator (hence 1 or 10k) so I changed them and even the arduino board
Is there any way to check if it's burned or not?
and they a sold out at my local dealer here
