Maybe some of you thought about how to let some RaspberryPi’s communicate with each other wirelessly. For this purpose small 433MHz modules are ideal, which are already available for a few bucks.
Therefore in this tutorial I want to show how two (or more) RaspberryPi’s can “talk” with each other. But do not worry, if you have only one Raspberry Pi, you can do it also.
WiringPi is a library that is used by many applications on the Raspberry but is not available by default. Especially many examples from the Arduino (C ++ code) can be performed easily on the RaspberryPi. To do so, this valuable library was written.
