LCD text shifts whenever my relay turns on

good day sir, same issue here with yours, the only difference is that LCD doesn't display weird characters, but the text displayed on the LCD is indenting or moving one unit to the right.

Example :

ARDUINO FORUM

Result when a relay turns on:

ARDUINO FORUM

  • the text indents one unit to the right.

Do you how to solve this issue/problem ?
Thanks in advance :slight_smile:
