An introduction to electronic interfacing circuits

Wiring two non-compatible circuits requires an electrical connection method. The electrical connection method addresses control signal differences between the two non-compatible circuits. Electronic interfacing is an electrical wiring method that connects or links one circuit to another electrical device. Traditionally, there are two approaches to interfacing electronic circuits: input and output. Input interfacing is an electrical approach to adapting an electronic circuit’s output to the input of another circuit device. Output interfacing allows an electronic or electrical circuit to control a real-world device. A real-world device such as an electromechanical relay, a discrete LED, or a liquid-crystal display (LCD) is wired to the output of a controller or switching circuit. The input and output electronic interfacing circuits traditionally use basic components, such as resistors, capacitors, or transistors. The arrangement...
