| Description | This LCD 16x2 White on Blue Display is a small HD44780-based screen capableofdisplaying up to 16 characters and 2 lines in alphanumerical or JapaneseKanacharacters, with space for up to 8 extra characters or symbols or“Foreigncharacters” of your choice as well. Thanks to the serial input I2Cbackpackthat is preinstalled on this display unit, it can be operated via only4 pins(VCC, GND, SDA, SCL), making it ideal for small projects in which usablepincounts are low, but the project still requires its own IndependentVisualInterfaces. The serial module is a LCM1602 using a PCF8574T controller IC
The blue backlight current is less then 40mA for this LCD. One of the unique benefits of this LCD is that it utilises a singleLEDbacklight that can be dimmed with a resistor or PWM, making it farmoreenergy-efficient than EL or electroluminescent backlights. This, inadditionto the very simple and easy-to-understand circuitry, makes it avaluableaddition to both beginners’ and veterans’ projects – since itoffersexceptional functionality without being overly complicated, energy-hungry, orhard to integrate into a project. Another unique feature of the HD44780 LCD is that it can also display eithera208 character 5x8 matrix or a 32 character 5x10 matrix as well, andratherthan having characters on the screen you can display graphics like abattery-indicator, arrows or any other imagery that you want to manuallydesign. This,in addition to the 9,920-bit character generator ROM and 240character fonts,make this LCD surprisingly versatile in its displayfunctionality.

As such,thisdisplay has been used for projects like: - Building a display for proximity sensors on a vehicle, with a bar to show how close or far away from objects the sensor is.
- Making a piggy bank that tracks and displays the amount of collected spare change, with an alarm and graphics to tell you when it’s getting full.
- Designing a weather tracker that displays the current temperature, humidity and amount of sunlight – and possibly even opens or closes the windows for you.
Whether your project simply requires a small amount of text when a buttonispressed or if it needs to constantly display real-time stats, theHD44780LCD16x2 White on Blue Display is the ideal choice in terms of value formoney.Additionally, this LCD is included in our Arduino Kits, which provide agreatstarting toolbox for a beginner, or can add to the ever-growing toolboxof aveteran Maker.
