Arduino data retention

Projects Programming

in short, incoming data data = 5592332 . I want to keep this data temporarily and rewrite it to the serial monitor when the button is pressed. but long data= mySwitch.getReceivedValue(); I can't retrieve the data because the variable is inside the if

#include <RCSwitch.h>
int buton=8;

RCSwitch mySwitch = RCSwitch();

void setup() {
  Serial.begin(9600);
  mySwitch.enableReceive(0);
    
  
}

void loop() {

 if (mySwitch.available()) {
    long veri= mySwitch.getReceivedValue();
    Serial.println( mySwitch.getReceivedValue() );
    mySwitch.resetAvailable();
    delay(3000);
    

}
 if(buton==HIGH){
 Serial.println(veri);

 }
}

In short, this is not and installation question…

I moved your post to a better place.

do yourself a favour and please read How to get the best out of this forum and modify your post accordingly.

Read about variable scope and declare your variable at the right level. When you get new data set a flag and make sure there is nothing blocking the loop

Didn't I just answer this question, but where you talk about the EEPROM feature you aren't using?

int buton=8;
...
 if(buton==HIGH){
...

So, you are saying "if 8==HIGH" ???
