Description: Reading analog means obtaining a continuous signal value from an analog sensor. This process is fundamental in electronics and programming, as it allows microcontrollers to interact with the physical world through sensors that generate analog signals. Unlike digital signals, which can only have two states (high or low), analog signals can represent a continuous range of values. This is crucial for applications requiring precise measurement, such as temperature, light, or pressure. In the context of microcontroller programming, the analog reading process is performed through the analog input pins, which convert the analog signal into a digital value that can be processed. This value is typically expressed in a range from 0 to 1023, where 0 represents 0 volts and 1023 represents the maximum reference voltage, usually 5V. The ability to read analog signals allows projects to be more versatile and sensitive to environmental variations, facilitating the creation of interactive and automated devices.
