hii i am creating project based on tx rx and buzzer.
i want to start my buzzer when my tx goes to x distance
can anyone please help me to write code

If you mean that you need the code then that is not generally how this forum works unless you are willing to pay for it for which purpose there is a particular forum category for it
The general forum works best by users writing code and seeking help with problems. That way you learn much more than by just copy/pasting code
What programming experience do you have and why did you choose this project ? Is it by any chance an assignment from school or college ?
I would not be thinking about distance I would be thinking about signal loss. Buzz when signal loss. You have no idea how far that will be and you will not be able to link the signal strength to distance in any meaningful way as there are too many compounding variables.
I would start by looking at examples in the ide and working through them until you have a basic knowledge of code then determine what is within your range of abilities as a project. Work on simple blocks, not the whole project at once. Draw detailed schematics. Save code iterations regularly with new and sensible names
Come back when you have something with any specific problems
ok what type of solutions can i take.
i have one in mind is that
i can measure the dealy of rx like how much time it take to receive the signals at what distance and then i can refer them to when buzzer should start.
what you think is it possible to do or its not......
Not easily done. In order to measure the time from the transmitter sending a signal to the receiver detecting it, the receiver would need to know EXACTLY when the transmitter sent the signal. How would you do that?
If you have your heart set on doing a distance measurement, then do a ping measurement.
The sender sends a signal and starts a timer.
The receiver detects the signal and transmits an acknowledge back to the sender.
The sender receives the ACK from the receiver and stops the timer.
The sender can then calculate the distance using the round-trip time.
However, the system clock in the Arduino family may not be fast enough to get meaningful data. Must it be on an Arduino board or can it be a different board programmed on the Arduino IDE? If the latter, I would look at the ESP32 board. It and it's little brother based on the ESP8266 (Wemos D1 Mini) . Both use an 80MHz clock as opposed to the 16MHz clock on Arduinos.
You are over thinking things. Start working through basics and once you know what is possible then develop a project. Randomly plucking ideas out of thin air is not a route to success.
