One of the many advantages of the Raspberry Pi is that it is possible to connect almost all standard Arduino and Raspberry Pi sensors and components to the various GPIOs. Moreover you can evaluate and / or process the values with programs and other software. This accessory can be used in projects such as Smart Home (home automation), robot kits or weather stations, etc.
This article describes and summarizes over 50 of the most important sensors and components for Raspberry Pi’s as well as Arduinos and provides you with a full Raspberry Pi sensor list.
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.
