Hey Guys! I have and Arduino Mega and a LCD1x6 working togheter to display a simple "Hello world"

The thing is that when I plug a soldering, iron or anytghing with power the LCD goes garbled. I red something about preventing electrical noise, but I could not find  anything helpfull so far.

Any help will be appreciated

Thanks!

@knut

Since he didn't identify his display how can you tell which character set it contains?

What would the character set have to do with noise?

What does that link have to do with noise?

There have been lots of posts about similar topics.  Look for posts with LCD and either garbled characters, weird characters, strange characters or something similar in the heading. 

Generally speaking the solution typically involves a capacitor or capacitors across pins 1 and 2 of the LCD module.
