I bought 433Mhz RF module (see image), reciever and transmitter.
I also have 433Mhz dimmer for LED strip (see image).
Using the receiver module I recorded the RF signal output from the dimmer remote and easily managed to send it via the transmitter module from Arduino.
My problem is that I need to control 2 dimmers from Arduino seperately. Is there any way to change the RF code in one of the dimmer's receiver so when I transmit codes from Arduino it'll affect only one dimmer?
