Today it is 13th of September and today is the programmers day and I am going to celebrate by posting a new tutorial that I´ve saved in my notes so hopefully, it will help other programmers.
If you have problems with this post or just wants to avoid adds, please visit my medium link
In this tutorial, I am going to show you how you can send data wirelessly between an Arduino to a BBB (Beagle Bone Black) using the Xbee module (although you can easily replace the BBB for another board like Rasberry or another Arduino)
What is the project going to do?
First, the circuit will read the humidity and temperature using the digital DHT11 sensor that is connected into the Arduino, then using the Xbee module it will send the data wirelessly to the other Xbee that is connected to the Beaglebone. Finally, the Beaglebone will read the data using a python programming language.
