Serial Protocols
Serial protocols are communication standards that transmit data sequentially, one bit at a time, over a single channel or wire. They are fundamental in embedded systems, IoT devices, and hardware communication, enabling devices like sensors, microcontrollers, and peripherals to exchange information reliably. Common examples include UART, SPI, I2C, and RS-232, each with specific characteristics for speed, distance, and complexity.
Developers should learn serial protocols when working with embedded systems, IoT projects, or hardware interfacing, as they are essential for device-to-device communication in resource-constrained environments. They are used in applications such as robotics, industrial automation, and consumer electronics to connect components like displays, sensors, and memory chips efficiently. Understanding these protocols helps optimize data transfer, debug hardware issues, and design interoperable systems.
