Crystall ball project lcd showing only blue screen

Hei I tried to chrck wires and code but nothing maybe u can help? Ty :smiley-

Imho your post looks as a crystal ball to me -

  1. what exactly is your configuration,
  2. what devices are involved,
  3. how did you wire them
  4. how does your sketch look like
  5. what do you expect how it should work
  6. what does work, what not ?
