Nrf24l01 problem occured

hey guys im having another problem now with my nrf24l01 it doesetn seem to work im trying to get my 2 joysticks to control my 4 servos wirless and the wirless module doesent seem to work is compiles and uploads fine and everything is on but nothing happens.
transmitter code

/*
---- Transmitter Code ----`Preformatted text`
*/

#include <SPI.h>`Preformatted text`
#include "RF24.h"

int joystick[6];

RF24 radio(7,8);                   
                                      
const uint64_t pipe = 123456;`Preformatted text`

void setup(void)
{
  radio.begin();
  radio.openWritingPipe(pipe);
  pinMode(2, INPUT_PULLUP);
  pinMode(3, INPUT_PULLUP);
}

void loop(void)
{
  joystick[0] = analogRead(0);  
  joystick[1] = analogRead(1); 
  joystick[2] = analogRead(2);
  joystick[3] = analogRead(3);
  joystick[4] = digitalRead(2);
  joystick[5] = digitalRead(3);
  radio.write(joystick, sizeof(joystick) );
}

and yes, I'm trying to use code tags

and heres the receiver code

Your topic was MOVED to its current forum category which is more appropriate than the original as it has nothing to do with Installation and Troubleshooting of the IDE

Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'

Use code tags (the </> icon above the compose window) to make it easier to read and copy for examination

does anyone have an answer

WOW !

You waited a whole 7 minutes before bumping this topic. Start by adding the code tags to make examining and copying your code easier

What have you tried so far to check that your radio modules are working?

Have you read through the excellent nRF24L01 tutorial? If not, I would recommend that you start here:

Check your wiring and head to post 30 for the checkconnection.ino sketch.

Once you have the basics working, slowly add in your required functionality, making sure that you test at each step.

The receiver does not use radio.read(), as far as I can see.
The transmitter misses a radio.stopListening() for the newest version of the library.
Using uint64_t for the pipe addresses is deprecated.
