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. in Finland and/or other countries worldwide.Raspberry Pi has a plethora of applications and a huge range over which it can be put to use, for some of these applications we require to connect it to external sensors or devices.
