Analog vs Digital Pins are fundamental in electronics and microcontrollers, with distinct roles. Analog pins measure continuous signals, like varying voltages from sensors, converting them into digital values using an Analog-to-Digital Converter (ADC). These are ideal for temperature, light, or sound measurements. On the other hand, digital pins work with discrete states: HIGH (1) or LOW (0). They are used to control LEDs, switches, or read binary inputs. Understanding analog and digital pins helps in designing versatile circuits for projects like robotics, IoT, and automation. Choosing the right pin depends on the application's input or output requirements.
