Question about the NRF24L01

Projects General Guidance

Hey all,

First off I just want to say I don't know if this is the correct place for this question, I didn't really know where to put it, so I apologize on that. Secondly, I had a question about the NRF24L01 transceiver module. If I were to set up multiple around a room or something like that, like if I had one in the center as a transmitter, and three others as receivers, is it possible to choose where to send data between those receivers? Like say I want one of the receiver's lights to turn on, it does that, but then the next second the transmitter sends data to a different receiver, which turns a fan on or something. Is that possible? Or do you have to have a transmitter and receiver for each one, which would then mean I have to have six. And say if I was able to use one transmitter for all receivers, what board should I use? I just need something simple, like powering or pressing something and that is it. If it is possible, please explain if you can. Please get back when you can, and thanks for your time.

Here is the Amazon link to the module:

You connect Tx/Rx with addresses and you can change those dynamically so you can have one transmitter talk to one receiver and then connect to a different receiver and repeat...

It is possible with any nRF board.
