950726 – LCD DISPLAY 16X2 IIC/I2C BLUE BACKLIGHT COMPATABLE W/ARDUINO
The LCD1602 16×2 I2C Blue LCD Display provides a 16 character x 2 line LCD with I2C interface for easy control by a microcontroller.
KEY FEATURES
- 16 character x 2 line Blue LCD
- I2C interface
- Adjustable backlight intensity and contrast
- 5V operation
These displays are straightforward to use and are a great way to
provide a user interface on many projects where you need more info than
simple LED indicators or 7Segment displays can provide since these are
full alphanumeric displays with 2 lines of 16 characters each. For an
interactive display pairing this type of display with a rotary encoder
to navigate and select menu items on the display can provide a very nice
user interface.
LCD Display
The display is composed of a 16 character x 2 line LCD display with a
blue backlight and white characters.  Each of the characters are
composed of a 5 x 8 dot matrix for good character representation.
The backlight has a potentiometer for adjustment of the contrast of the display for best viewing.
The backlight intensity is not directly controllable though the I2C
interface however there is a jumper on the I2C board that supplies
power to the backlight. That jumper can be removed and a voltage
applied to the header pin nearest the ‘LED’ markings on the board to
provide power to the backlight separately.
The backlight can go down to about 3V before it goes out. It is not
known what the safe upper limit is for driving the LCD backlight so it
is probably best not to exceed 5V by too much. At 5V the backlight
draws about 20mA so it should also be possible to drive it with a PWM
pin off a microcontroller to allow the display to be dimmed via software
if desired.
