This circuit is simply an example of what you can do.
In the breadboard diagram, you can use any parts you like (any power source, any microcontrollers, any connector,)
But you have to use a 5vdc activated relay in order to work with the microcontroller.

The schematic is correct, but ATTINY13 should be ATTINY85
Antenna should be about 6.8 inches long.
the PCB in the fzz is not correct.
fzz is opened with Fritzing software

RXPCB files are correct, remember to print ACTUAL SIZE.
.rrb file can be opened with Robot Room's Copper Connection software.
