Having two or more Arduino boards be able to communicate with each other wirelessly over a distance opens lots of possibilities like remotely monitoring sensor data, controlling robots, home automation and the list goes on. A good, reliable and inexpensive solution is NRF24L01.

The NRF24L01+ is a newer version of the NRF24L01, capable of doing an extra 250kbps of on-air data rate while the one without “+” has only 1Mbps and 2Mbps. Both versions can be mixed together as long as 1 or 2 MBps is being used as the data rate.

Digital communication between devices is an essential part of modern technology. There are several protocols available for this purpose, each with their own strengths and weaknesses. Three of the most commonly used protocols are UART, I2C, and SPI. In this article, we will examine these three protocols, their advantages and disadvantages, and how they compare to each other.

Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language and the Arduino Software (IDE).
