Hi Guys i need your help.
I have a Projekt with a lot of simple Sensors and with 3 Arduinos. My idea is that one Arduino is a Master and the other two Arduinos are the Slaves, BUT the Slaves talk back to the Master with the updated values or with other values.
I dont know how i can make this communication happend. I tried wireless over Radio but the Receiver cant talk without a Timing parallel with two Transmitters.
The next idea was a Serial communication (TX,RX) but is this possible to code with the sensor values exchange?
Another idea was a CanbusShield. Whats your experience with that one?
Thank you for your help! (sorry for the bad english)
Best regards from Germany
