#include "RF24.h"
byte data[1];
const uint64_t Pipe = 0xF0F0F0F0A1LL;
RF24 radio(9,10); // CE,CSN:

void setup() {
pinMode (4,INPUT_PULLUP);
pinMode (5,INPUT_PULLUP);
pinMode (6,INPUT_PULLUP);
pinMode (7,INPUT_PULLUP);
Serial.begin(9600);
radio.begin();
radio.openWritingPipe(Pipe);
}

void loop() {
if(digitalRead(4)==HIGH||digitalRead(5)==HIGH||digitalRead(6)==HIGH||digitalRead(7)==HIGH){
data[0]=0;
}

}
