Serial Communication is a protocol in an embedded system for communication between the microcontroller based devices like arduino and raspberry pie to other peripheral devices supporting the serial communication protocol. This protocol is also known as UART or USART(universal asynchronous receiver/transmitter). It follows the UART protocol It is very popular because it uses only two wire for communication the digital pin 0(RX) and digital pin 1(TX). When using serial communication these two pins can’t be used as the digital pins.
When [Bill Porter] works on a project, he says that he typically writes his own NMEA standard communications protocols to fit the job at hand. While it makes things easy to troubleshoot, he admits that his custom protocols are wasteful of both processor time and bandwidth. Binary communications on the other hand are more efficient, but a bit trickier to manage. To make things easy for the common user, which abstracts packetized serial communications between two Arduino boards. The process is pretty simple – all one has to do is define a data structure on both Arduino boards so that they know what sort of data is coming over the wire, and EasyTransfer handles the rest.
This allows users to worry less about communications protocols or transmission errors, and focus on their projects instead. If you’re working on a project and searching for an easy way to get a pair of Arduinos talking, swing by his site and grab the library. It doesn’t get much easier.

Thanks for the post Mike, though I really didn’t think this warranted a full post, I was only hoping to be in the next ‘Arduino Moment’ combo article. I wrote this in a day as a way to help out the handful of people that email me asking for help getting one Arduino with a PS2 controller (using my other library) to talk to the other. It’s a simple library with not much to it. How To Whatsapp On Nokia E5 For.
Most Arduino user will undoubtedly know how to handle communications. This library is nothing special; it was targeted for the extreme beginner with no idea how to begin.
