    Thank you very much. I thought it has no problem since the pins are connected to the LCD image.

    Thanks again

    The pins are connected to the LCD? Is it soldered on the backside and we just can't see?

    No, no. Nothing is soldered. What I mean is that I thought it has no problem since the header is connected to the LCD. By the way I am programmer and I almost know nothing about electronics. So, I am sorry for my silly questions. Last thing, do you have the time to explain me why soldering is important?

    The connection is not made until it soldered.

    At the moment its a very poor and intermittant joint between the header pins and the lcd.

     

    The breadboard has contacts that 'grip' the pin and therefore make contact.

    If you wish to avoid having to solder there are several alternatives.

    There is an LCD shield available that includes some pushbuttons and is designed to go onto the Arduino.

     

    There is also some I2C LCD's and I use these. http://yourduino.com/sunshop2/index.php?l=product_detail&p=331

    A 4 pin lead is all you need to connect since they have a small extra board that converts the I2c data to the display.

     

    Sadly element14 don't carry them and it would be very useful to their range.
