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.

  • addressing the slaves is on you. or use ModbusRTU – Juraj Feb 21 at 13:47

  • @Juraj : any particular library? – JavaEnthusias Feb 21 at 14:23
  • You need to implement one of automation protocols or write your own. en.wikipedia.org/wiki/List_of_automation_protocols – smajli Feb 21 at 15:22
