Hey I'm looking for some guidance on an approach to my project.
The idea is to have 1 rf remote with multiple buttons
And several receiver units capable of pairing e.g. can be set so one button can control several units or one button per unit at the users choice.
I'm fairly new to arduino and totally new to RF builds
This Simple nRF24L01+ Tutorial may give you some ideas. Communication betweeen nRF24 modules depends on the sender and receiver using the same channel and the sender knowing the address of the receiver. You could have several receivers listening on the same address or your sender could send the same message to each receiver separately if the receivers have unique addresses.
