What is UART?

UART (Universal Asynchronous Receiver/Transmitter) is a hardware communication protocol that enables asynchronous serial communication. It transmits data one bit at a time, without a clock signal, using start and stop bits to synchronize the data flow between the sender and receiver. UARTs are commonly used for low-speed, short-distance communication between microcontrollers, computers, and peripherals like sensors, GPS modules, and Bluetooth devices.
