Raspberry Pi with OS installed (available on the official website).

Asynchronous serial communication is widely used for byte oriented transmission. Raspberry Pi uses UART (Universal Asynchronous Receiver/Transmitter) is a serial communication protocol in which data is transferred serially i.e. It is also a simple, yet effective method of communication and is easy to learn and master for beginners. Serial communication is a widely used approach to transfer information between a system and peripherals connected to it. To do this, we use the GPIO pins provided on the board, and by the end of this article, you should be able to connect your Raspberry Pi to any serial device.

Using serial communication with your Raspberry Pi is a simple and efficient way to read and write from and to an external device. To do so, we need to first understand how to connect the Pi to read and write from the peripheral device.
