Analog Input
What is an analog input?
An analog input is a pin or channel on a microcontroller, development board, or data acquisition system that can read continuously variable voltage signals. It uses an analog-to-digital converter (ADC) to convert the incoming analog voltage into a digital value that can be processed by the microcontroller. Analog inputs are commonly used to read sensors like temperature sensors, potentiometers, light sensors, and other devices that output varying voltage levels rather than simple on/off digital signals.
