## How does the LCD 1602 work?
### Answer:
The LCD 1602 (16 characters x 2 lines) is a commonly used alphanumeric display in electronics projects. It works by displaying information on a screen made of liquid crystal material. There are two main components: a liquid crystal display (LCD) module and a driver circuit. The driver circuit sends electrical signals to the LCD module, causing the liquid crystals to align and display characters. The characters are formed by selectively turning on and off pixels arranged in a grid pattern. The display is usually controlled by a microcontroller, which sends data and commands to update what is shown on the screen.
