Working Principles

The PCM1602KY module utilizes a liquid crystal display (LCD) to generate characters on its screen. It operates by applying electrical signals to control the alignment of liquid crystal molecules, which selectively block or allow light to pass through. The module receives data and commands from a microcontroller or other controlling device through its parallel interface, and then displays the corresponding characters on its screen.
