  • Arduino - Make a Wi-Fi/Ethernet Serial Converter almost 2 years ago

    Thanks :D. You are right, it is quite reasonable to directly use an Arduino RS232 port. But I am obsessed with nice wiring, so I chose a RS232 shield for that reason :D.

    Well, technically, yes. If the sensor doesn't use a very specific interface, then you probably can connect it with Arduino, but that may require some additional effort.
    It isn't clear to me which role does the ATMEGA play in your scheme, so I can't say anything about it. Anyway, almost everything is possible, the question is just how much does it cost to you to make it work :D
    Cheers

    Well, a flow sensor, an LCD screen, and 2 Arduino boards are needed of course. You will need one RF receiver and one RF transmitter module.
    Never done that before, but I guess it will be kind of:
    Flow sensor --> Arduino #1 --> RF transmitter -----------> RF receiver --> Arduino #2 --> LCD
    That's probably all the hardware stuff you need.
    Cheers :D
