Wireless Printer and Keyboard Design is a document available to read on EtoBox.

This document describes the design of a wireless printer and keyboard using infrared (IR) communication. It includes block diagrams and circuit diagrams of the IR transmitter and receiver components for both the printer and keyboard. The printer uses an 89C51 microcontroller to transmit and receive data to and from the keyboard via IR signals. Similarly, the keyboard uses an 89C51 microcontroller and IR components to wirelessly transmit keyboard inputs to the printer. The design allows the printer and keybo
