How does this differ for a 14pin LED Board? I'm assuming to use the same first 3 and last 2 pins and will be testing this out later. Thank you and take care

سلام علیرضا. به ال سی دی که دارم درایور لحیم شده. برق رو با درایور بهش دادم و یه منفی هم به پایه وی او. درست کار میکنه. ولی وقتی از میکرو بهش دیتا میدم فقط ال ای دی نور روشن میشه. اگر از منفی میکرو به وی او یه جامپر بزنم تکست رو برای یه لحظه نشون میده ولی بعدش کل بلاک روشن میشه. مشکل از درایوره؟

@@kian.smarthome the problem was with the wiring they weren't well connected, had to solder them into the LCD as the LCD I got didn't have pins pre-soldered in it
