IS SOLDERING NECESSARY FOR LCD

Hi. I have been working with an LCD and using the diagram and code from the link below. I edited the code and made it work for my computer and adding the LiquidCrystal.h library and program is compiling and uploading to my Uno. But as I turn the potentiometer from one far side to the other, not a single thing happens. Is it because I had not soldered the pin headers to the LCD even though I am making metal to metal contact with the two? Or do I have to move the potentiometer differently. THANK YOU!!

Soldering is absolutely neceessary - but SHOUTING isn't.

I wouldn't use the code provided at that site for your first LCD project. I suggest a simple message generated in setup() with loop() left empty.

Ok. I will have to look into the supplies. Thank you!!! @floresta !
