LCD Display

A 16×2 LCD display is an electronic display module commonly used with Arduino and other microcontrollers to show text, numbers, symbols, and sensor readings. The name 16×2 means that the display has 16 characters in each row and 2 rows, allowing it to display up to 32 characters at a time. It can be used in projects such as temperature monitors, digital clocks, smart home systems, robotics, and sensor-based projects. A 16×2 LCD can be connected directly to a microcontroller using several pins, or an I2C module can be attached to reduce the number of connection pins required.
