nrf24l01 not sending simple PWM

Hello Im trying to get these nrf24l01 transceivers to dim an LED wirelessly for some reason NOTHING !
here is my Code

any Help would be great im out of ideas ?

[/c//-Transmitter 


#include <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"

int pot_pin = A5;
const byte address[6] = "00001";
RF24 radio(7,8);
// Set up nRF24L01 radio on SPI bus plus pins 7 & 8 (CE & CS)
int volts ;


void setup() {

radio.begin();
//radio.setPALevel(RF24_PA_LOW);
//radio.setDataRate(RF24_250KBPS);
radio.setChannel (75);//Set Channel from 0-127
radio.openWritingPipe(address[6]);
radio.stopListening();
pinMode(pot_pin, INPUT);

}

void loop() {
volts = map(analogRead(pot_pin),0,1024,0,254); 
radio.write(&volts,sizeof(volts) );
delay(20);
}

int LED = 9;
byte address[6] = "00001";
RF24 radio(7, 8);
// Set up nRF24L01 radio on SPI bus plus pins 7 & 8 (CE & CS)
int volts ;

void setup() {
  pinMode(LED, OUTPUT);

  radio.begin();

  //radio.setDataRate(RF24_250KBPS);
  radio.setChannel (75);//Set Channel from 0-127
  radio.openReadingPipe (0, address[6]);
  radio.startListening ();
}

void loop() {
  /*
    digitalWrite(LED,HIGH);
    delay(500);
    digitalWrite(LED,LOW);
    delay(500);
  */
  if (radio.available()) {
    radio.read(&volts, sizeof(volts));
    //volts = map(volts, 0, 254, 0, 1023);
    delay(50);
    analogWrite(LED,volts);
  }

Put a Serial.begin(9600) in setup so that you can use a Serial.print to see what you are receiving. The serial port is your best troublshooting tool.

Use the examples in the simple rf24 tutorial to get the radios working and gain a better understanding of how they work.

This certainly won't work. Study the example code, and array indexing basics.

radio.openWritingPipe(address[6]);

 radio.openReadingPipe (0, address[6]);

Im no pro with these radios . Im learning thoe

this is code I borrowed from somewhere do you have any Idea What I should change this to

radio.openReadingPipe (0, address[6]);

The examples linked in reply #1 show how to do it correctly.

address[6] is not defined, and is an illegal reference to memory that you do not own.

ok ill give it a shot ...Thanks

well That didn't work im just trying to dim an LED wirelessly ..how hard is that ? lol

What did you try and what were the results? "Didn't Work" is probably the most piss-poor problem statement you could have come up with.

363 posts and that is the best you can do?

Please read and follow the directions in the "How to use this forum" post.

That gives us no useful information from which to help you.

Have you tried the examples in this Simple nRF24L01+ Tutorial for which you were given the link in Reply #1?

Wireless problems can be very difficult to debug so get the wireless part working on its own before you start adding any other features.

The examples are as simple as I could make them and they have worked for other Forum members. If you get stuck it will be easier to help with code that I am familiar with. Start by getting the first example to work
