Specifica despre ce LCD este vorba, ma refer la modelul acestuia, sau pune aici un datasheet pentru el.De obicei ultimii pin tin de backlight, iar led-ul de backlight are de obicei nevoie de un rezistor extern, dar valoarea acestuia nu e chiar aleatoare... de asta avem nevoie de datasheet.

Daca este standard, atunci are nevoie de 4,2V pentru backlit. Pui o dioda 4148 de la +5V si s-a rezolvat. Am folosit aceasta metoda cu success in multiple proiecte.

Dacă ai lumină şi rezistenţa nu fumegă, toate bune :)
