I am try to send very basic signal between 433Mhz Transmitter and Receive ..... simple boolean of On/Off and just with single channel.....
I see many tutorial online but for complex set up using the Arduino or Decoder and using many channel.
This basically be remote control On/Off switch for device that transmitter sit between, with Relay to do power switch. Garage door open is same idea.
Can signal be receive without use of decoder or Arduino? I know can do easy with use of decoder HT12E and HT12D but seems like too much for how simple.... If possible please let me know step to take to receive signal without and what needed for to transmit binary On\Off signal thank you for help.
