Tons of lib are existing to use RF transmiterreceiver here is 2 which are interesting. Pin definitions for the Raspberry Pi WiringPi project. The Raspberry Pi is an amazing 35 dollars minicomputer. It allows you to do everything you could do with a regular Linux computer Connecting to the internet. I choose RCSwitch because of the Raspberry Version. And this lib is directly compliant with a lot of RF standard devices I will make a post about that laterArduino. The lib is responsive for everything and it is really easy to use.

Here is the code to send message Here we can send bytes with a common protocol hardcode in the lib. RCSwitch my. Switch RCSwitch. Serial. begin9. 60. WiringPi is a PIN based GPIO access library written in C for the BCM2835 used in the Raspberry Pi. Its released under the GNU LGPLv3 license and is usable from C.

Ok now, Raspberry Pi is ready to receive command. Start the ArduinoNext. Plans for next steps are. Sniffing existing devices to reverse command signal. Using this communication way to send data from Arduino sensor such as electrical consumption sensor to Raspberry in order to monitor sensors from the web.
