Abstract: UART- Universal Asynchronous Receiver Transmitter, generally it is used for better transmission of serial data that is it either transmit or receives data serially with the help of shift register. It consist frame format, one start bit (usually low), 5-8 data bit, one optional parity bit and one stop bit (opposite polarity of start bit). Asynchronous means by using start and stop bit we transmit data, there is no need of sending (PAD) that is ASCII (SYN) for synchronizing transmitter and receiver. It transmits 9600 to 38400bps for transmitting data bit. Whole process of serial transmission is based upon the principle of shift register.
