My Arduino gesture control project

Using Arduino Project Guidance
#1

My car with the receiver makes a beeping noise when I turn it on. I uploaded the code already but I'm not sure what the beeping sound is. any help? Also uploaded my code to the transmitter but doesn't seem to move the car. Would really appreciate the help. (beginner)

receiver code//
#include<SPI.h>
#include<nRF24L01.h>
#include<RF24.h>

int ENA = 3;
int ENB = 9;
int MotorA1 = 4;
int MotorA2 = 5;
int MotorB1 = 6;
int MotorB2 = 7;

RF24 radio(8, 10);

const byte address[6] = "00001";

struct data {
int xAxis;
int yAxis;

};
data receive_data;

void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
radio.begin();
radio.openReadingPipe(0,address);
radio.setPALevel(RF24_PA_MIN);
radio.setDataRate(RF24_250KBPS);
radio.startListening();
pinMode(ENA, OUTPUT);
pinMode(ENB, OUTPUT);
pinMode(MotorA1, OUTPUT);
pinMode(MotorA2, OUTPUT);
pinMode(MotorB1, OUTPUT);
pinMode(MotorB2, OUTPUT);
}

void loop() {
// put your main code here, to run repeatedly
while(radio.available()) {
radio.read(&receive_data, sizeof(data));
if(receive_data.yAxis > 400) {
digitalWrite(MotorA1, LOW);
digitalWrite(MotorA2, HIGH);
digitalWrite(MotorB1, HIGH);
digitalWrite(MotorB2, LOW);
analogWrite(ENA, 150);
analogWrite(ENB, 150);

}else if(receive_data.yAxis < 320) {
digitalWrite(MotorA1, HIGH);
digitalWrite(MotorA2, LOW);
digitalWrite(MotorB1, LOW);
digitalWrite(MotorB2, HIGH);
analogWrite(ENA, 150);
analogWrite(ENB, 150);
} else if(receive_data.xAxis < 320){
digitalWrite(MotorA1, HIGH);
digitalWrite(MotorA2, LOW);
digitalWrite(MotorB1, HIGH);
digitalWrite(MotorB2, LOW);
analogWrite(ENA, 150);
analogWrite(ENB, 150);
}else if(receive_data.xAxis > 400){
digitalWrite(MotorA1, LOW);
digitalWrite(MotorA2, HIGH);
digitalWrite(MotorB1, LOW);
digitalWrite(MotorB2, HIGH);
analogWrite(ENA, 150);
analogWrite(ENB, 150);
}else {
digitalWrite(MotorA1, LOW);
digitalWrite(MotorA2, LOW);
digitalWrite(MotorB1, LOW);
digitalWrite(MotorB2, LOW);
analogWrite(ENA, 0);
analogWrite(ENB, 0);
}
}
}

Transmitter code//
#include<SPI.h>
#include<nRF24L01.h>
#include<RF24.h>

const int x_out = A0;
const int y_out = A1;
RF24 radio(8,10);
const byte address[6] = "00001";
struct data{
int xAxis;
int yAxis;

};
data send_data;

void setup() {
// put your setup code here, to run once:
radio.begin();
radio.openWritingPipe(address);
radio.setPALevel(RF24_PA_MIN);
radio.setDataRate(RF24_250KBPS);
radio.stopListening();
}

void loop() {
// put your main code here, to run repeatedly:
send_data.xAxis = analogRead(x_out);
send_data.yAxis = analogRead(y_out);
radio.write(&send_data, sizeof(data));
}

Can you check the schematic or wiring diagram after you upload the program to the arduino , cause a small mistake of connection can make a big difference .

if the uploading is done than it is almost done just cross check the wiring diagram and your connection
