joystick module and RC motor

Hello,

I could need some help!. I'm trying to controll speed on a RC motor with a Joystick module and a NANO
card. I got everyting working but the joystick is to sesitive. Smallest movment on the joystick and the motor goes to top speed. I need help so i can use the hole scale on the joystick for trootle "only use x axis". is it programing or modification on boards?

Please help

What joystick module, what motor, what code?

You may need to change the mapping in the code you did not post.

Thank you!!!....here is the code.

#include <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"4L01.h"
#include "RF24.h"
#include "printf.h"
#include "printf.h"
//
// Hardware configuration
//
// Set up nRF24L01 radio on SPI bus plus pins 9 & 10
RF24 radio(9,10);

uint8_t data[2]; //buffer to store received data
const uint8_t buffer_size = sizeof(data);
//pins that used for the Joystick
const int analogInPinY= A0; //
const int analogInPinX = A1;//
const int StearRight = 3;
const int StearLeft = 5;
const int tx_led=2;// transmission indicator
int Y_value = 0; // values read from the pot
int X_value = 0;
int outputValue = 0;
/*
const int transmit_pin=6;
int transmit_enable;
int ForwrdButton=2;
int BackwrdButton=3;
*/
//
// Topology
//

// Single radio pipe address for the 2 nodes to communicate.
const uint64_t pipe = 0xE8E8F0F0E1LL;

printf_begin();

//
// Setup and configure rf radio

radio.begin();

radio.openWritingPipe(pipe);
//

//

radio.printDetails();

//
// Set up buttons

digitalWrite(tx_led,LOW);

digitalWrite(StearLeft,HIGH);

}

//
// Loop

void loop(void)
{

X_value = analogRead(analogInPinX);
data[0] = map(X_value, 0, 1023, 100, 200);

if(data[0]<100){
data[0]=100;
}

radio.write( data, buffer_size );

Serial.println(data[0]);
delay(10);
