This is a basic 20 character by 4 line display or 20×4. Interface code is freely available. You will need ~11 general I/O pins to interface to this LCD screen. Includes LED backlight.
If you want to add some visual output to your Arduino projects, you’ll need a display. If you need moderate data on display, the LCD2004 Parallel LCD Display is a quite good solution for the Arduino projects.
This is an industry-standard JHD629-204A based controlled 4 lines x 20 characters LCD display with Black characters on Green background. It is a parallel interface so you will need 7 pins for 4-bit mode or 11 pins for 8-bit mode to interface to this LCD screen.
