The board offers a 2x16 LCD display with white backlit blue writing with the HD44780 standard. The contrast can be adjusted using the trimmer. There are also 6 buttons acting on analogue pin A0 through a resistive partition.
The board consists of an alphanumeric 16 × 2 LCD display and 5 buttons. Each button on the LCD Keypad is connected to a series resistance with that of the previous button, you will find this ingenious choice because in this way with only one analog pin (A0) you can recognize the pressure of one of the 5 buttons simply by reading the reading value on that Pin from Arduino's 10Bit DAC (digital analog converter).
