One TX and many RX

Hi:

I know nothing about using 433 MHZ TX/RX with Arduino, but this simple question will clarify the concept: can I use a single TX and some RX providing I send specific words ("commands") that every RX knows if it must comply or ignore?

Thanks,
Robert

I have no experience with 433MHz wireless but you can certainly do what you say with nRF24L01+ transceivers.

If you are only interested in 433MHz wireless (which would be a perfectly reasonable thing) please modify your Original Post and add "with 433MHz wireless modules" to your title.

It would also be a good idea to post a link to the datasheet for the modules you plan to use.
