This is an amazing 16x2 LCD display screen with an I2C interface. It can show 16x2 characters on two lines, featuring white characters on a blue background. In Arduino LCD display projects, pin resources often run out quickly, especially with Arduino Uno. Also, wire soldering and connection are quite complex. But this I2C 16x2 Arduino LCD Screen uses an I2C communication interface. It only needs 4 pins (VCC, GND, SDA, SCL) for the LCD display, saving at least 4 digital/analog pins on Arduino. All connectors are standard XH2.54 (Breadboard type), so you can connect with jumper wires directly. To prevent I2C address conflicts with other I2C devices like ultrasonic sensors, IMUs, accelerometers, and gyroscopes, the I2C address of the module is configurable from 0x20 - 0x27. You can also manually adjust its contrast. If you need to display more characters, there's an alternative option - the I2C 20x4 Arduino LCD Display Module. The last update was V1.2. Specifications: Compatible with Arduino/Genuino UNO, Leonardo, Mega, 101 (Intel Curie), Micro, Nano, Mini. I2C Address: 0x20 - 0x27 (0x20 default). Back lit (Blue with white char color). Supply voltage: 5V. Interface: I2C/TWI x1, Gadgeteer interface x2. Adjustable contrast. Size: 82x35x18 mm (3.2x1.4x0.7 in). Documents include Wiki, Schematic, Arduino I2C 1602 LCD Library, Sample code, and HD44780 LCD datasheet. Shipping list: One I2C 16x2 LCD Screen (Arduino Compatible).
Using this I2C 16x2 LCD display for Arduino is easy. First, connect the 4 pins (VCC, GND, SDA, SCL) to your Arduino board using jumper wires as the connectors are breadboard - type. You can power it with a 5V supply. If you have other I2C devices, make sure to set the I2C address of this module between 0x20 and 0x27 to avoid conflicts. You can adjust the contrast manually to get the best display effect. When it comes to maintenance, keep it in a dry and clean environment. Avoid exposing it to extreme temperatures. If you need more help, refer to the included Wiki, Schematic, and sample code. And if you want to display more characters, consider the I2C 20x4 Arduino LCD Display Module.
