Well, im new in this arduino stuff.
You get the hole story.
My father in law have a holiday house which have a heating system in the living floor witch can be turned on and off by a Gsm( sms ) module.
The module just sends a minus 12 v out when it receives a sms ( plus 12 v i a common for the outputs )
Is it possible? or should i say how is it possible. Ive bought some 433mhz receivers and transmitters. I would like to wirelessly turn radiotor on in another room.
Can that be done with these transmitter modules ?
Like im giving the transmitter a 1 in the data pin, will it then give a 1 the reciever with can trigger an optocoubler and then a relay for the radiotor?!?
