I want to make a prosjekt where my Arduino Uno sends bluetooth signals to multiple bluetooth receivers for light relays, is this possible?
The idea is to control multiple light sources around the apartment.
Is there any bluetooth modules that can do this?
Thanks!
Bluetooth is typically a 1-1 pairing.
You might be able to find a module that supports IEEE-802.15.1 and a "piconet" for multiple connections.
NRF24s are made for this sort of thing and have mau7ch same cost and performance.
