I'm new to github and arduino, but using _LiquidCrystalI2C lcd(0x27, 16, 2); causes an error on NodeMCU boards (and maybe others) but not on Mega 2560. The workaround is to replace it with _LiquidCrystalI2C lcd(0x27); and add lcd.begin(16,2); in setup. Maybe this is obvious, but it confused me a lot, and the error message was very unhelpful. ("Invalid Converson from ‘int’ to ‘t_backlighPol" [-fpermissive]")
