A light pen is an optical device that detects light emitted by a computer screen to determine the position of the pen on the screen. It is used as an input device to interact with computers by pointing, clicking, and drawing on the screen.
A light pen works by detecting light emitted by a computer monitor or screen when the pen's tip touches the surface. The pen has a light-sensitive photodiode at the tip, which detects the light and sends a signal back to the computer to identify the pen's position on the screen. This allows users to interact with software by pointing and selecting on the screen.
The biggest advantage of having a pen is its portability and convenience. Pens are easy to carry around and use without the need for additional equipment. Additionally, pens allow for quick and precise writing on various surfaces.
