Wireless robot hand (nRF24l01)

I have built a wireless robot hand for school project using flex sensor, nRF24l01 module and servo but it is not working.
I have reassembled it many times and assembled it again but still it is not working. Please help me.

And please also check the circuit diagram.

Here is the code :

Reciever code :

#include <Servo.h> //the library which helps us to control the servo motor
#include <SPI.h> //the communication interface with the modem
#include “RF24.h” //the library which helps us to control the radio modem

//define the servo name
Servo myServo1;
Servo myServo3;
Servo myServo4;
Servo myServo2;
Servo myServo5;

RF24 radio(5,10); /This object represents a modem connected to the Arduino.
Arguments 5 and 10 are a digital pin numbers to which signals
CE and CSN are connected.
/

const uint64_t pipe = 0xE8E8F0F0E1LL; //the address of the modem,that will receive data from the Arduino.

int msg[1];

int data; //data variable
int pos; //position variable

void setup(){

//define the servo input pins
myServo1.attach(15); //A1
myServo3.attach(16); //A2
myServo4.attach(17); //A3
myServo2.attach(18); //A4
myServo5.attach(19); //A5

radio.begin(); //it activates the modem.
radio.openReadingPipe(1, pipe); //determines the address of our modem which receive data.
radio.startListening(); //enable receiving data via modem
}

//You don’t need to make changes in this section
void loop(){
if(radio.available()){
radio.read(msg, 1);

if(msg[0] <11 && msg[0] >-1){
data = msg[0], pos=map(data, 0, 10, 175, 0);
myServo1.write(pos);
}
if(msg[0] <21 && msg[0]>10){
data = msg[0], pos=map(data, 11, 20, 175, 0);
myServo3.write(pos);
}
if(msg[0] <31 && msg[0]>20){
data = msg[0], pos=map(data, 21, 30, 175, 0);
myServo4.write(pos);
}
if(msg[0] <41 && msg[0]>30){
data = msg[0], pos=map(data, 31, 40, 175, 0);
myServo2.write(pos);
}
if(msg[0] <51 && msg[0]>40){
data = msg[0], pos=map(data, 41, 50, 175, 0);
myServo5.write(pos);
}
}
}

And Transmitter code :

#include <SPI.h> //the communication interface with the modem
#include “RF24.h” //the library which helps us to control the radio modem

int msg[1];

//define the flex sensor input pins
int flex_5 = A5;
int flex_4 = A4;
int flex_3 = A3;
int flex_2 = A2;
int flex_1 = A1;

//define variables for flex sensor values
int flex_5_val;
int flex_4_val;
int flex_3_val;
int flex_2_val;
int flex_1_val;

RF24 radio(5,10); //5 and 10 are a digital pin numbers to which signals CE and CSN are connected.

const uint64_t pipe = 0xE8E8F0F0E1LL; //the address of the modem, that will receive data from Arduino.

void setup(void){
Serial.begin(9600);
radio.begin(); //it activates the modem.
radio.openWritingPipe(pipe); //sets the address of the receiver to which the program will send data.
}

void loop(){

flex_5_val = analogRead(flex_5);
//175 - 0
flex_5_val = map(flex_5_val, 1023, 0, 0, 10);
msg[0] = flex_5_val;
radio.write(msg, 1);

flex_4_val = analogRead(flex_4);
//175 - 0
flex_4_val = map(flex_4_val, 1023, 0, 11, 20);
msg[0] = flex_4_val;
radio.write(msg, 1);

flex_3_val = analogRead(flex_3);
//175 - 0
flex_3_val = map(flex_3_val, 1023, 0, 21, 30);
msg[0] = flex_3_val;
radio.write(msg, 1);

flex_2_val = analogRead(flex_2);
//175 - 0
flex_2_val = map(flex_2_val, 1023, 0, 31, 40);
msg[0] = flex_2_val;
radio.write(msg, 1);

flex_1_val = analogRead(flex_1);
//175 - 0
flex_1_val = map(flex_1_val, 1023, 0, 41, 50);
msg[0] = flex_1_val;
radio.write(msg, 1);
}

The code you posted improperly does something.
You expect it to do something.

Only YOU know what either of those things are.

The code IS working. That it does not meet your expectations means that your expectations are wrong.
