I have made one project that is two BO dc Motor (300rpm) and one servo controlled by remote (nrf24l01) with joy stick and buttons
I have used two push button this controlled motor 2 rotation i.e, clock and anticlockwise.
I have used joy stick ,X axis controlled Motor 1 rotation i.e, clock and anticlockwise.Y axis controlled servo
I have used L298N Motor driver for two motor.
I used the NRF24L01 with 3.5volt adaptor.
Two number External dc power supply (230AC-24VDC-5A) with Buck converter (3A) used for TX and RX circuit seperately.
Now coming to my problem.
If i have controlled the Motor2 by push button and servo controlled by joy stick (Yaxis), system working satisfactory.
But when i controlled the BO motor by the joy stick(Xaxis) ,the connection between the TX and RX is disconnected shortly after the operation.Than RX i has to be again to start work again.
My TX code is here
#include <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"
#define CE_PIN 9
#define CSN_PIN 10
#define yAxis A0 // A0 for Arduino UNO

// NOTE: the "LL" at the end of the constant is "LongLong" type
const uint64_t pipe = 0xE8E8F0F0E1LL; // Define the transmit pipe
/*-----( Declare objects )-----*/
RF24 radio(CE_PIN, CSN_PIN); // Create a Radio
/*-----( Declare Variables )-----*/
int joystick[6]; // 10 element array holding Joystick reading and 4 buttons
int HstUp = 2;
int HstDwn = 3;
void setup() {
Serial.begin(9600);
radio.begin();
radio.openWritingPipe(pipe);
pinMode(xAxis,INPUT);
pinMode(yAxis,INPUT);
pinMode(HstUp,INPUT_PULLUP);
pinMode(HstDwn,INPUT_PULLUP);
delay(1000);
}
void loop() {
radio.stopListening();
radio.write( joystick, sizeof(joystick) );
joystick[0] = analogRead(xAxis);
joystick[1] = analogRead(yAxis);

Serial.println (joystickY);
servoVal = joystickY; // scale it to use it with the servo (result between 0 and 180)
myservo1.write(servoVal);

}
I don't know whether the problem in my code .Expecting valuable advice from the arduino Forum members.
Thank you
