What Is an Electronic Pin?
An electronic pin is a terminal provided on devices such as integrated circuits and microcontrollers. It’s a small-sized metal component that plays critical roles in both digital and analog signal processing. Digital pins on microcontrollers serve as conduits for transmitting and receiving electronic signals, facilitating tasks like digital input/output, interrupt signal generation, and communication with other devices via protocols such as I2C or SPI.
Conversely, analog pins are designed for managing analog signals, enabling the reading of analog data from sensors or controlling actuators like motors and LEDs through analog output.
