Serial Communication Protocol
Serial communication protocol is a method for transmitting data sequentially, one bit at a time, over a communication channel or computer bus. It enables devices like microcontrollers, sensors, and computers to exchange information using standards such as RS-232, UART, SPI, and I2C. This protocol is fundamental for embedded systems, IoT devices, and hardware interfacing where simple, reliable data transfer is required.
Developers should learn serial protocols when working with embedded systems, IoT devices, robotics, or any hardware that requires communication between microcontrollers, sensors, or peripherals. It is essential for debugging hardware via serial consoles, interfacing with legacy industrial equipment, and building low-cost, wired communication systems in projects like Arduino or Raspberry Pi.
