Serial communication is one of the ways in which Microcontrollers communicate data. In this type of communication, data is transferred bit by bit over a single wire.

For example if a microcontroller 1 is transferring data to another microcontroller 2 in serial form then TXD pin of microcontroller 1 will be connected to RXD pin of microcontroller 2 and data will be transferred from microcontroller 1 to microcontroller 2 in bit by bit manner over a single wire.
