What a nuisance. Damn, I'm having a problem with Arduino Nano to load a code I created for a project. The code compiles it perfectly but it gives me an error:
avrdude: ser_open (): can't open device "
I tried everything !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I restarted the computer, changed the port, tried to do with the Mega but with the same problem.
My only hope is you guys.
Sorry if I didn't greet you at first.
Code:

#include <SPI.h>
#include "RF24.h"
const int buz=7;
RF24 radio(13,12);
const uint64_t pipe=0xE8E8F0F0E1LL;
void setup()
{
Serial.begin(9600);
pinMode(buz, OUTPUT);
radio.begin();
radio.openReadingPipe(1, pipe);
radio.startListening();
}
void loop() {
int a;
if(radio.available()){
radio.read(&a, sizeof(a));
if(a==1){
digitalWrite(buz, HIGH);
delay(250);
digitalWrite(buz, LOW);
delay(250);
}else{
digitalWrite(buz, LOW);
}
}
}

Now it gives me another problem:

WHY??????????????????????????

Hello - you give a lot of information - but the most important are missing.

  • Windows can show in the Device Manager, if an Arduino is present (or not).
  • Did you select a not working programmer in the IDE menu?
  • Did you select the "Old Bootloader" for a older Nano?
  • The link in the last line of your error messages may help too.

Thank you very much but I solved it.
I changed the cable because the one I used was an old one with a "choke" but now I used the cable suitable for Arduino and it works.
