I am not experienced in the communication between arduinos to send data. So I was wondering if it is possible to let 3 arduino mega send data to each other.
All 3 arduino mega have the same purpose. The reason I need 3 of them is because I need 160 I/O and 40 Analog inputs. I know other boards/plc can be used aswell but i found this more quick to program for myself and has a faster devilery time. It will be used in my final school project.
The data the arduinos need of each other is a simple high or low state. When a sensor gets the correct value the other arduinos need to know this, because of the timing.
Also because communication has a sort of delay I was wondering if anyone knows what it is, because the system i'm making requires a precision of 0,1ms. So if the communication has a time of lets say 10ms, I know where I have to put my sensors.
I hope you guys understand and can help me a bit out how to let 3 arduino mega communicate with each other.
