Need two different designs for a wireless link. Thinking about using these
https://www.sparkfun.com/products/8945
https://www.sparkfun.com/products/10533
One app is a On/OFF control of a pic circuit.
second app is three switches and send via wireless link which switch has been closed.
The data sheet for the transmitter / receiver show an ic from Holtek but source?
Laipac tech which sells the transmitter / receiver want $40 min order and $40 shipping.
Found same at Sparkfun for less $$
Contemplating maybe DTMF might be a method but have never worked with DTMF , RX, TX circuits. Been finding circuits but locating a parts source??
Any suggestions??
