GREAT ! i think to 1
That shows you understood the story
Thank you very much , i have one more question about the lcd, its serial so it needs TX and RX , 0 and 1 pins of my arduino... I want to connect a gsm shield , which needs TX and RX pins too...
As i found out , pins 0 and 1 are the hardware serial ... If i want to connect another serial device i will have to see http://www.arduino.cc/en/Reference/SoftwareSerial in order to make , lets say pins 2 and 3 , software serial and then i will have 2 serial working devices .. is that right ? thanks !
