I have some question to arduino arduino communication. I hope someone can help me.
My problem is i want to make a master slave communication. For the master i want to use an arduino Feather M0 Bluetooth. The Arduino Feather is calcuating the weight of water. important is that die Master is sending the weight to a seperated arduino via bluetooth. the seperatet arduino will have a lcd on which you can read the weight.
Now my question is what typ of arduino i will need to make a network between the two. and how i can program the master slave relation.
thanks for the help.
