OK here is the UNO hookup.
My time is now 16:14 and this is the result of the i2c-scanner sketch:
15:56:35.589 ->
15:56:37.029 -> I2C scanner. Scanning ...
So it has been scanning for approximately 18-19 minutes with no result. Does this mean the LCD or the i2c adapter is bad? I have no knowledge about this matter.
Thank you.
