* This sketch simply repeats data received from remote weather sensors made by Cresta.
|
|
*
|
|
* Setup:
|
|
* - connect digital output of a 433MHz receiver to digital pin 2 of Arduino.
|
|
* - connect transmitter input of a 433MHz transmitter to digital pin 11
|
|
* - An LED on pin 13 will tell you if and when a signal has been received and transmitted.
|
|
*
|
|
* Library:
|
|
* https://github.com/mattwire/arduino-dev/tree/master/libraries/RemoteSensor
|
|
* https://github.com/LSatan/SmartRC-CC1101-Driver-Lib
