Chapter Content
Component: Analog/Digital I/O
Role: Signal interfacing
Example Applications: Sensors, actuators
Detailed Explanation
I/O modules serve as critical interfaces between processing units and external devices. Digital I/O handles simple on/off signals while analog I/O accommodates variable signals that may represent physical quantities like temperature or pressure. They are essential for collecting data and executing actions based on the signals received.
Examples & Analogies
You can think of I/O modules like translators in a multi-language meeting. They convert verbal signals (analog/digital) from different languages (sensors/actuators) into a common language that the central processor can understand and act upon efficiently.
