👉 Analog I/O (Input/Output) refers to a method of interfacing digital electronic devices with analog signals, which are continuous and vary smoothly over time, such as those found in sensors measuring temperature, pressure, or sound levels. Unlike digital I/O, which uses discrete binary states (0s and 1s), analog I/O allows for the direct reading and writing of continuous values. This makes it ideal for applications where precision and smooth data representation are crucial, such as in audio processing, medical instrumentation, and control systems. Analog sensors convert physical phenomena into electrical signals that can be processed by digital circuits, but they maintain the inherent continuity of the analog signal, ensuring minimal loss of information during conversion.
