Hi I'm super new at arduino and actually don't yet own any bits and pieces, I'm still reading alot of intro tutorials to get my head around it first
I've got this concept I want to build when I'm more adept
Cheap 433mhz button transmitters, where when you press the button it triggers the arduino to send audio phrases to my Bluetooth speaker and possibly also text to an Android phone (text matching the recorded audio phrases)... I basically want to use this concept so my dog can press buttons that tell us what he needs
I'm also trying to figure out how to connect all of our google home speakers so if you transmit bluetooth to one all of them will play the sound just so the dog could press his buttons in his bedroom and I could hear it on my google home in my room which is deffs out of bluetooth range
I've run through so many potential smart concepts for communication buttons but this one seems possibly feasible
Has anyone used 433mhz buttons and remotes with arduino to trigger actions
Welcome to the Arduino forum. I am sure you will have lots of fun. I am using 433mHz buttons for a non-Arduino project to release doors on a bird trap so they can be caught and banded.
Beware!!!! the 433 push buttons emit a UNIQUE code for each button made. No two will have the same code. The receiver must be programmed to recognize a particular button's code. In my case, the receiver has a push button to ready the receiver to accept the code from the next button to be pressed. Once programmed, it will not respond to another button.
The particular receivers I am using actually have three possible programs and for two of them, it can be programmed to recognize TWO different buttons. One button to turn a relay on and the other button to turn a relay off. I am not using that option, only the first option.
I think it would be REALLY hard to program an Arduino to duplicate my receiver functions.

Yes I know they emit a unique code which is kind of the appeal because I could have 50+ buttons.... Possibly needing to use one arduino per button
I wonder if it might be possible with a raspberry pi instead of arduino
I know that you can replicate a 433mhz unique code using arduino and send that onto another arduino or a raspberry pi with a message of sorts
Potentially simply using a regular old touch button to trigger an arduino with a unique signal to send on a message
I've tried to think of any sort of wireless button idea where a central hub receives the signal and performs an action.... I looked at the homey hub as an option for that but it requires compatible devices and an app per sort of device.... Thought about zigbee hubs but would need a good number of repeaters for extra buttons and devices
So I came back to 433mhz buttons as I figured there would need to be a way to build or find a receiver that can perform an action per signal programmed into it
But I could simply go back to a "dumb" version of the concept and build a button panel that uses several adafruit sound FX boards and a regular speaker an a bluetooth transmitter on a splitter
