# kuneRF
A really basic RF 433MHz switch for a 4 channel relay module.
This will save and restore states from EEPROM when powercycling the Arduino. (So, like turning lights on or off.)
| PIN | function |
|--|--|
| D2 | RF receiver input |
| D3 | Relay #1 IN |
| D4 | Relay #2 IN |
| D5 | Relay #3 IN |
| D6 | Relay #4 IN |
Remote values are hard-coded into the code, you may need to change those.
const unsigned long COMMANDS_ON[] = {
1064981, // relay 1
1052693, // relay 2
1069077, // relay 3
1066005 // relay 4
};
const unsigned long COMMANDS_OFF[] = {
1064980, // relay 1
1052692, // relay 2
1069076, // relay 3
1066004 // relay 4
};
To get codes, use the RCSwitch library's ReceiveDemo sketch on your Arduino.
