Radio transmitter with feedback function

Hello everyone,
I need a programming help for my radio transmitter project. I have already implemented a radio transmitter (Nano) and a receiver (Uno) on 433 Mhz. Pressing a button on the transmitter then triggers a relay on the receiver. This works too. I would now like to add a feedback function. This means that when the relay on the Uno (receiver) switches, an LED should light up on the Nano (transmitter), for example for 5 seconds. A kind of feedback function.

Previous sketches (codes) for the transmitter-module and receiver-module are available and can then be transmitted for modification.

Beste regards,
Toby

Unless you can identify them as something special, all 433 devices are TRANSCEIVERS, meaning the can both transmit and receive, but not both at the same time. So, anything you can transmit on one device you can transmit on the other, and vis-versa.
If, the devices are really individual transmitter and receiver, you will have to get new devices that are transceivers

Are you able to say which 'radio transmitters' you are using ?

There are lots of different 'radio transmitters' out there.
