The LCD 1602 Parallel LCD Display is a simple and cost-effective solution for adding a 16×2 white-on-black Liquid Crystal Display to your project. It features 16 characters and 2 lines of clear, high-contrast black text on a green background, making it ideal for Arduino-based projects.
This green backlight LCD display is easy to interface with Arduino and other microcontrollers. Unlike traditional LCD 1602 displays that require about 8 pins, this model includes an I2C adapter directly soldered to the pins, allowing you to connect just the I2C pins, simplifying wiring and reducing coding requirements.
I2C is a serial bus developed by Philips that uses two bidirectional lines, SDA (Serial Data Line) and SCL (Serial Clock Line), both requiring pull-up resistors. It operates with standard 5V or 3.3V voltages.
With the I2C adapter already integrated, setup is easy with only four pins to connect: VCC, GND, SDA, and SCL. The display can show simple text, numerical values from sensors (e.g., temperature or pressure), or track the number of cycles your Arduino is performing.
