What is the use of USART?

USART (Universal Synchronous/Asynchronous Receiver-Transmitter) is a hardware communication protocol used for serial data transmission. It allows for both synchronous and asynchronous communication, enabling devices to exchange data over short or long distances efficiently. USART is commonly utilized in microcontrollers and embedded systems for tasks such as debugging, data logging, and interfacing with other devices like sensors and displays. Its versatility and simplicity make it a popular choice in various applications.
