PS2KeyboardInterface

In this project, an interface between a PS2 keyboard and PIC16F877A is implemented. The main goal of this project is to use a computer keyboard with any instrument without needing a computer. keyboards are basically connected via either USB or PS2. In this project, PS2 Keyboard is interfaced with PIC16F877A. PS2 connector has 6-pin Mini-DIN […]

In this project, a temperature meter is designed and implemented to measure the temperature a room, or outside. There are a large variety of temperature sensors, in this project LM35 is used, I choose that sensor for several reasons. These reasons are: precision integrated-circuit temperature sensors. its output voltage is linearly proportional to the Centigrade temperature. it has […]

An oscilloscope is a type of electronic test instrument that allows observation of constantly varying signal voltages, usually as a two-dimensional graph of one or more electrical potential differences using the vertical or ‘Y’ axis, plotted as a function of time, (horizontal or ‘x’ axis). Although an oscilloscope displays voltage on its vertical axis, any […]
