Hi. I've finally got the Nokia LCD i've ordered from Sparkfun: http://www.sparkfun.com/commerce/product_info.php?products_id=8600 Then i followed the guide on Arduino Playground: http://www.arduino.cc/playground/S1D15G10NokiaLCD/S1D15G10NokiaLCD and made the transistor voltage divider using - 4 BC547 - 4 470Ohm Resistors - 4 4.7K Resistors
Then i used the 3V3 pin on the Arduino to get the 3.3V, and then i connected everything as shown. Then i programmed the Arduino using the example code, and when it was programmed nothing happend! The LCD was only Purple and hummed very much (caused by the backlight StepUp converter)
I have tried to find the problem, but I can't! If i disconnect the LCD and the I/O lines from the Arduino, and then connect to test the voltage deviders, the output is 3.25-3.27V when I apply 5V - so no problem there!
