I am using Arduino Uno as a Master Device and 3 Arduino Unos as slave devices.
I am sending data from each slave to master after every 3 seconds continuously, and is going to execute further logic accordingly.
I have been using a lot of libraries to test this scenario. There are libraries which are using SoftwareSerial and HardwareSerial too, but these libraries are not working for me when i have multiple slaves and one master (It is only working with one master and one slave).
Please suggest me a better library which would be useful in my scenario.
