I am new in electronics and I bought Arduino starter kit with UNO board. I was trying to connect the LCD display but there was a problem. I did the exact connection that there is in the libraries LiquidCrystal, the backlight opened but no text in the display. Can anyone tell me what is happening? I am trying to understand but I have no idea.
Thank you all for your answers! I found out what was the problem. The potentiometer hasn't installed properly.. When I installed it correctly and then adjust brightness with the trim of the potentiometer, everything work properly!!
