Display the customer chars

You can also make the LCD to display your own chars or logos as you like, you need to constrat your own chars in your program, as the method in the "CustomChars" demo. also, it would be easy for you to make the LCD display what you input with the serial port, just as the "SerialDisplay" demo, you can sent what you want to display with the serial monitor in the Arduino IDE, please note that you should set the baudrate to 9600. for me, i want the I2C LCD 1602 to show "good day".

The Backlight can be controlled by the firmware or the on-board jumper:
Firmware:
 

 lcd.backlight();// light on the backlight;
 lcd.noBacklight();//light off the backligth;


Hardware:
There is a jumper on the board, if you take away this jumper , the backlight will aways be off:
