I am trying to interface my Uno R3 board to this LCDhttp://media.nkcelectronics.com/datasheet/LCM1602K3-NSW-BBW.pdf
Using the Example in the Liquid Crystal I2C Library "Hello World" all i get is a bunch of meaningless characters on the screen.
I have checked that the correct pins are connected and that R2 jumper is soldered for I2C comm.
Is their something i am missing ? ? ?
LiquidCrystal_I2C lcd(0x19,16,2); // set the LCD address to 0x19 for a 16 chars and 2 line display
lcd.init(); // initialize the lcd
// Print a message to the LCD.
