Popular alphanumeric LCD display, powered with voltage 5 V. It is characterized by its simplicity, availibility and the numerous support for many microcontrollers.
The product is compatible with Arduino
In the standard set of libraries and sample programs downloaded with the environment of Arduino, is the library LiquidCrystal which provides support for the display.

The display can be controlled in the following modes:
- 8-bit without the reading of the busy flag - to transmit, the eight data bus lines and two control lines (RS, E - RW connected to ground) are required.
- 8-bit with the reading of the busy flag - to transmit, the eight data bus lines and three control lines (RS, E, RW) are required.
- 4-bit with reading of the busy flag - to transmit, the four lines of the data bus and three control lines(RS, E, RW) are required.
- 4-bit without reading of the busy flag - to transmit, the four lines of data bus and two control lines (RS, E - RW connected to ground) are required.
The most frequently selected method of communication is the 4-bit mode without reading of the busy flag. Sending a half-byte allows you to save valuable leads I/O of microcontroller - only four data lines (in 8-bit eight of them are busy) are used. Lack of the reading of the busy flag introduces the need to use software delays but allows you to save another line - R/W. Pin can be connected on a permanent basis to the masses because the data will be delivered only in one direction, to display.
