There are many ways to communicate with remote Arduinos. I have found that many of them hit a slightly higher price point than what I would like. Also, ethernet shields (and wifi dito?) consume many valuable hardware pins. I will describe how to communicate host to Arduino using commercially available wireless serial ports. They are cheap(ish) and only use the rx/tx pins. The drawback is that the air-protocol isn't encrypted so I wouldn't use it for sensitive applications. I use it to control lighting. I would be more impressed than offended if a neighbour hacked my indoor lighting. Serial ports (even wireless) are designed for point to point communication. It is possible to use in one-to many or other constellations but certaing design consideration have to be taken. My Arduino library referenced in step 5 supports one-to many.
The described project is for one-way or two-way communication using (i. e. transciever). If you know you will only send commands 'blindly' you can attach a transmitter to the PC end and a receiver to the Arduino. Those modules are really cheap.
In this tutorial, we will explore the use of Serial Communication in Arduino Uno. Arduino has built-in support for UART which enable serial communication. UART as a serial protocol is most useful and famous protocol. The Arduino can transmit and receive data to the PC over USB Cable. Serial communication works on 1s and 0s. Also known as binary, the Arduino sends these 1s and 0s (bits) one by one, or Serially. These bits are sent in the form of Highs(1) and Lows(0). These bits form together and turn into bytes. A byte is composed of 8 bits. The Arduino Reference text is licensed under a Creative Commons Attribution-Share Alike 3.0 License. Find anything that can be improved?

Arduino Serial To Serial Communication Problems
Arduino serial Background of Serial Communication Example of serial port programming in Arduino three types of communication systems in serial communication. Serial communication (UART) is one of the most popular communication protocols. Most processors support this two-wire connection. Also, many of modules and sensors use serial communication to connect to the other devices. Serial communication requires only two wires; one for transmitting data and the other one for receiving it.
Dc Pandey physics mechanics part 2 PDF is the best book ever for a Serious IIT-JEE (Main, Advance) & Medical Student. It is the best book for you if you are preparing for JEE Main or Advance Seriously. The Understanding Physics Series authored by Mr. Pandey and published by Arihant has proven itself to be one of the excellent physics series for JEE Physics preparation in the previous years. There are five volumes in the series: Mechanics Part 1, Mechanics Part 2, Waves and Thermodynamics, Electricity and Magnetism, Optics and Modern Physics. Dc pandey physics book pdf bsc download 2016.
