  1. 0:00 At least if you ain't sure on how to spell enthusiasts go to a dictionary or just research it or let autocorrect deal with it. But that is just embarrassing

  4. If anyone is still having trouble, change lcd.begin to lcd.init, also, when you include the .zip library, you must INSTALL the library, goto library manager, type liquidcrystal_i2c into search and find the one by frank, select most recent version and install, this worked for me for the lcd.begin error
