I am using an uno and a joystick shield on the transmitter side while mega and l298n motor driver on the receiver side.
The codes are as follows:
Transmitter code:
#include <SPI.h>
#include "RF24.h"
int x_axis = A1;
int y_axis = A2;
int xvalue;
int yvalue;
int data[2];
RF24 radio(9,10);
const uint64_t pipe=0xE8E8F0F0E1LL;
void setup() {
Serial.begin(9600);
radio.begin();
radio.openWritingPipe(pipe);
}
void loop() {{
xvalue=analogRead(x_axis);
xvalue=map(xvalue,0,1023,0,127);
data[0]=xvalue;
radio.write(data,1);
}
{
yvalue=analogRead(y_axis);
yvalue=map(yvalue,0,1023,128,255);
data[0]=yvalue;
radio.write(data,1);
}
Serial.println(xvalue);
Serial.println(yvalue);
}
Receiver code:
#include <SPI.h>
#include "RF24.h"
const int motorforward = A1;
const int motorbackward = A2;
const int motorleft = A3;
const int motorright = A4;
int data[2];
RF24 radio(9,10); // CE,CSN:
const uint64_t pipe=0xE8E8F0F0E1LL;
void setup() {
pinMode (motorforward,OUTPUT);
pinMode (motorbackward,OUTPUT);
pinMode (motorleft,OUTPUT);
pinMode (motorright,OUTPUT);
Serial.begin(9600);
radio.begin();
radio.openReadingPipe(1,pipe);
radio.startListening();
}
void loop() {
if(radio.available())
{
Serial.println("RA");
}
else{
Serial.println("NA");
}
delay(1000);
if(radio.available()){
radio.read(data,1);
Serial.println("rcvd");
Serial.println(data[0]);
if(data[0]>1 && data[0]<51){
digitalWrite(motorforward,LOW);
digitalWrite(motorbackward,HIGH);
}
if(data[0]>77 && data[0]<128){
digitalWrite(motorforward,HIGH);
digitalWrite(motorbackward,LOW);
}
if(data[0]>52 && data[0]<76){
digitalWrite(motorforward,LOW);
digitalWrite(motorbackward,LOW);
}
if(data[0]>129 && data[0]<179){
digitalWrite(motorleft,HIGH);
digitalWrite(motorright,LOW);
}
if(data[0]>205 && data[0]<255){
digitalWrite(motorleft,LOW);
digitalWrite(motorright,HIGH);
}
if(data[0]>180 && data[0]<204){
digitalWrite(motorleft,LOW);
digitalWrite(motorright,LOW);
}
}
}

I have tried changing the mega with uno, replaced the jumper/rainbow cables, but the problem still persists.
